　　Overexcavation refers to the part of the actual excavated section outside the reference line based on the designed excavation contour line. Here are several common explanations:

　　1. Overexcavation in mining: In mining operations, overbreak refers to the situation where the actual volume of rock excavated exceeds the designed or expected excavation boundary during the excavation process. This may be due to the inaccuracy of drilling and blasting techniques, or intentionally done to ensure the stability of the working face. Overexcavation can lead to resource waste and additional costs, as it means extracting more rocks than ores.

　　2. Overexcavation of tunnels and underground engineering: In tunnel construction and other underground engineering projects, oversize or overbreak refers to the actual excavation size of tunnels or caverns being greater than the design size. This may be due to limitations in construction technology, such as insufficient drilling accuracy and improper blasting control. Overexcavation may lead to structural instability, increase support costs, and may require additional repair work.

　　3. Overexcavation under complex geological conditions: In some complex geological conditions, in order to ensure construction safety and structural stability, the construction party may intentionally carry out a certain degree of overexcavation. This can provide more space for subsequent support and lining work to cope with unforeseeable geological changes.

　　4. Overexcavation in construction: In above ground construction, over excavation may refer to digging deeper than the design depth during the foundation excavation process. This situation is usually caused by measurement errors, construction errors, or measures taken to solve foundation problems.

　　How to handle the over excavation part?

　　In basic construction, if over excavation occurs, corresponding measures may need to be taken, such as sand piles, cement fly ash piles, dynamic compaction method, replacement method, preloading method, etc., to ensure the bearing capacity and stability of the foundation.

　　In construction projects such as site excavation or tunnel excavation, there may be three situations: over excavation, under excavation, and exact excavation height. Over excavation requires backfilling of the site, while under excavation requires continued excavation, both of which result in wastage of manpower, material resources, and financial resources. In order to better control costs and schedule, construction workers usually set up temporary leveling elevations based on the site conditions, and promptly inform excavator drivers or laborers of the required excavation thickness according to the elevations.

　　Underexcavation is an engineering term that refers to the phenomenon where the perimeter of the cross-section of a shaft, tunnel, or other underground project is smaller than the design size after blasting. This term is mainly applied in fields such as coal mining, water conservancy and hydropower engineering, and highway tunnels.

　　In the construction of underground projects such as tunnels and tunnels, excavation is usually required according to the designed cross-sectional dimensions. However, due to various reasons, the actual excavated section may have some areas that do not meet the design requirements, which is called under excavation.

　　The reasons for under excavation may include: low drilling accuracy, resulting in the outer insertion angle, opening position, or drilling depth of the surrounding boreholes not meeting the requirements; Improper blasting techniques, such as unreasonable types and structures of explosives, unreasonable arrangement of surrounding holes, or unreasonable blasting design; Construction operations are not standardized, such as inaccurate contour lines, poor control of drilling positioning or drilling angle deviation, insufficient drilling or unauthorized reduction of drilling depth.

　　Underexcavation may bring some problems, such as affecting the quality and safety of the project, requiring additional treatment to meet design requirements, which will increase construction costs and time. In order to reduce the phenomenon of under excavation, a series of measures need to be taken during the construction process, such as improving drilling accuracy, optimizing blasting design, strengthening construction management and measurement work, etc.

　　For example, strengthening the training of drillers to enable them to master drilling techniques proficiently; Reasonably determine the depth of the borehole based on geological conditions and construction requirements; Carefully carry out drilling and blasting design, select appropriate explosive varieties and loading methods; Using high-precision instruments for measurement, accurately drawing excavation contour lines, etc. At the same time, it is necessary to strengthen inspections during the construction process, promptly identify and address any issues of under excavation.

　　In tunnel engineering, it is very important to control over excavation (actual excavation section exceeding the design size) and under excavation, which helps to ensure project quality, reduce costs, improve construction efficiency, and ensure the stability of surrounding rock.

　　Disadvantages: The quality of sprayed concrete is greatly affected by construction techniques and material mix proportions; High rebound rate may result in certain material waste; The technical requirements for construction personnel are high to ensure the uniformity and compactness of spraying.

　　4. Steel arch support

　　Advantages: The overall stiffness is relatively high, which has a good supporting effect on fractured rock or rock with low rock grades; Can be made and assembled on site, suitable for tunnels with different cross-sections and conditions; It can be well combined with other support methods such as anchor rods and shotcrete to work together and improve support efficiency.

　　Disadvantages: Large amount of steel used, relatively high cost; Installation requires a certain amount of time and manpower; The weight of steel arches is relatively large, and the transportation and installation process is relatively complex.

　　In practical engineering, one or more support methods are usually selected comprehensively based on the specific geological conditions, surrounding rock types, tunnel uses, construction methods, and other factors of the tunnel to achieve safe, economical, and reasonable support effects. At the same time, monitoring and measurement during the construction process are also very important. Based on the monitoring results, support parameters can be adjusted in a timely manner to ensure the stability and safety of the tunnel.

　　When tunnel construction is carried out in soft rock areas, special techniques and materials are required to ensure construction safety and long-term stability of the tunnel due to the low strength, high compressibility, and easy deformation of the rock. Here are some commonly used techniques and materials:

　　Technologies required for tunnel construction in soft rock areas:

　　1. Shotcrete support: The use of Shotcrete technology can quickly provide temporary support structures to prevent rock loosening and collapse. Shocked concrete can be directly sprayed onto the tunnel wall to form a continuous and uniform support layer.

　　2. Steel arch support: In soft rock, steel arch support is a common way of support, which can provide immediate structural support and be combined with sprayed concrete to increase overall stability.

　　3. Anchor rods and cables: By installing anchor rods or cables in the surrounding rock, the rock can be fixed together, improving the overall bearing capacity of the surrounding rock. These anchor rods or cables are typically used in conjunction with shotcrete and steel arches.

　　4. Freezing method: In extreme soft rock environments, such as clay and sand with extremely high moisture content, the freezing method can be used to temporarily freeze the formation, forming a sturdy shell for tunnel construction.

　　5. Grouting reinforcement: By injecting cement slurry or other types of chemical slurry into the surrounding rock, cracks and pores can be filled, improving the strength and stability of the rock.

　　6. Step by step excavation method: Using step by step excavation techniques such as the New Austrian Tunneling Method (NATM), the excavation and support steps can be flexibly adjusted according to the conditions of the surrounding rock to maintain the stability of the tunnel.

　　Materials required for tunnel construction in soft rock areas:

　　1. High performance shotcrete: Using shotcrete with high early strength and high fluidity can provide sufficient support strength in a short period of time.

　　2. High strength steel: Steel used for manufacturing steel arches and anchor rods needs to have high strength and good toughness to withstand stress and deformation in soft rock.

　　3. Rapid setting cement slurry: The cement slurry used for grouting reinforcement needs to have the characteristic of rapid setting in order to quickly improve the strength of the surrounding rock.

　　4. Chemical grouting materials: In addition to traditional cement slurry, various chemical grouting materials such as epoxy resin, polyurethane, etc. can also be used, which can better penetrate small cracks and provide effective reinforcement effects.

　　5. Anti leakage materials: Waterproofing and anti-seepage are important considerations in the construction of soft rock tunnels. Various anti-seepage membranes, coatings, and sealants can be used to prevent groundwater infiltration.

　　When carrying out tunnel construction in soft rock areas, engineers need to choose the most suitable combination of technology and materials based on specific geological conditions, construction equipment, and budget factors. At the same time, it is necessary to closely monitor the deformation and stress changes of the surrounding rock, adjust the construction plan in a timely manner, and ensure construction safety and long-term stability of the tunnel.
