Detailed implementation manners

[0025] Geotechnical engineering is an important branch of civil engineering, mainly studying the mechanical properties of rocks and soils and their interaction with engineering structures. It involves the analysis, design, construction and monitoring of engineering problems such as foundations, slopes, tunnels, retaining walls, underground structures, etc., aiming to ensure the safety, stability and economy of engineering structures. Mechanical properties of geotechnical materials: Soils: Study the physical properties of soil (such as density, water content, void ratio), mechanical properties (such as compressibility, shear strength) and their changes over time (such as consolidation, creep). Rock masses: Analyze the strength, deformation characteristics of rocks and the influence of joints and fractures on the stability of rock masses. Foundation and subgrade engineering: Foundation bearing capacity: Determine the bearing capacity of foundation soil under load to prevent foundation settlement or instability. Foundation design: Select appropriate foundation forms (such as shallow foundations, deep foundations) according to the foundation conditions and carry out design calculations. Slopes and retaining structures, Slope stability analysis: Evaluate the stability of natural or artificial slopes under the action of factors such as gravity, groundwater, earthquake, etc. Retaining wall design: Design retaining walls to resist earth pressure and prevent soil mass from slipping. Underground engineering, Tunnels and underground spaces: Study the disturbance of tunnel excavation to the surrounding geotechnical mass and design support structures to ensure construction safety. Foundation pit engineering: Analyze the deformation and stability of soil mass during the excavation of deep foundation pits and take support measures. Geotechnical engineering investigation and testing, Site investigation: Obtain the physical and mechanical parameters of geotechnical mass through drilling and in-situ tests (such as standard penetration test, plate load test). Laboratory tests: Conduct mechanical tests on soil samples and rock samples to provide a basis for design.

[0026] Application fields of geotechnical engineering: Construction engineering: Foundation design for high-rise buildings and large factories. Transportation engineering: Subgrades of highways and railways, bridge foundations, tunnel engineering. Water conservancy engineering: Foundation treatment and slope stability of dams, dikes, and reservoirs. Environmental engineering: Impermeability and stability analysis of landfills and nuclear waste disposal sites. Energy engineering: Drilling and exploitation of oil and natural gas, development of geothermal energy. Challenges faced by geotechnical engineering: Uncertainty of rock and soil masses. The properties of rock and soil masses are affected by factors such as geological structures, history, and environment, showing large variability. Probability analysis, reliability design, and other methods are needed to deal with uncertainty. Complex engineering conditions, treatment of special soil bodies such as soft soil foundations, expansive soils, and collapsible loess. Engineering design and protection in areas with high seismic intensity and prone to landslides. Environment and sustainable development, reducing the damage of projects to the environment, such as avoiding groundwater level decline and land subsidence. Promoting green geotechnical engineering technologies, such as soil improvement and ecological slope protection. Development trends of geotechnical engineering: Numerical simulation and artificial intelligence, using numerical methods such as finite element and discrete element to simulate the mechanical behavior of rock and soil masses. Combining machine learning and big data analysis to improve the accuracy and efficiency of geotechnical engineering design. Rock-soil-structure interaction, studying the interaction between rock and soil masses and structures (such as bridges and tunnels) to optimize the design. New geotechnical materials and technologies, developing high-performance geosynthetics and new foundation treatment technologies (such as vacuum preloading and dynamic compaction).

[0027] Geotechnical engineering is a discipline in civil engineering that is directly related to the natural geological environment, and its core is to solve the problems of "soil and rock". With the acceleration of urbanization and the continuous advancement of infrastructure construction, geotechnical engineering is playing an increasingly important role in ensuring project safety, improving resource utilization efficiency, and protecting the ecological environment. In the future, geotechnical engineering will pay more attention to technological innovation, sustainable development, and interdisciplinary integration, providing safer, more efficient, and more environmentally friendly engineering solutions for human society.

[0028] Application fields: Mine engineering is used for grouting reinforcement of fault fracture zones and fractured rock masses to prevent water hazards and improve the stability of surrounding rocks. Tunnel engineering is used for reinforcement and strengthening of tunnel fissures and fractured rock masses to prevent collapse and water seepage. For example, the grouting reinforcement technology for roadway repair in fault fracture zones can improve the state of rock and soil by grouting and control the deformation of surrounding rocks. Construction engineering is used for foundation treatment, slope stability, underground space development, etc. For example, the ground pre-grouting technology can significantly improve the strength and impermeability of fractured rock masses. Water conservancy engineering is used for impermeability treatment of dams, dikes, and reservoirs to ensure project safety.

[0029] Grouting method: Penetration grouting, under a constant pressure, the grout infiltrates into the fissures without damaging the formation structure, and is applicable to rock masses with relatively large fissure widths and good connectivity. Fracture grouting, through high pressure, the grout fractures the rock mass to form new grouting channels, and is applicable to low-permeability rock masses or situations where the grouting range needs to be expanded. Compaction grouting, injecting high-concentration grout, the rock mass is compacted through extrusion, and is applicable to loose rock masses or projects that require improving the strength of the rock mass. Filling grouting, the grout directly fills the fissures, and is applicable to projects with relatively large fissure widths and that require rapid curing. Grouting pressure needs to be determined according to the characteristics of rock mass fissures, the properties of the grout, and project requirements. Excessive pressure may cause the rock mass to rupture, while too low pressure cannot effectively fill the fissures. Grouting volume is determined through on-site tests or numerical simulations, and the aperture, connectivity of the fissures, and the diffusion radius of the grout need to be considered. The setting time of the grout needs to be adjusted according to the project progress and grouting effect. Rapid-setting grout is applicable to dynamic water conditions, and slow-setting grout is applicable to situations that require sufficient diffusion. Grouting sequence usually adopts the segmented downward grouting method, that is, grouting section by section from bottom to top to ensure that the grout diffuses fully and prevent ground heave.

[0030] The technology of grouting in rock mass fissures is an important means in geotechnical engineering. Its successful implementation needs to comprehensively consider the characteristics of rock mass fissures, the properties of grouting materials, grouting methods, and process parameters. In the future, with the continuous development of new materials, new processes, and new technologies, the technology of grouting in rock mass fissures will play a more important role in engineering practice.
