Slope support engineering is a technology widely used in civil engineering, geological disaster prevention, mining, railway and highway construction, etc. It aims to stabilize slopes through various engineering measures, prevent geological disasters such as landslides and collapses, protect people's lives and property, and ensure the normal operation of engineering facilities.

　　I. Common types of slope support

　　1. Soil nail wall support: by setting soil nails in the soil slope, it works together with the soil to improve the stability of the slope.

　　2. Anchor support: using anchors to transfer tension to stable strata to maintain the stability of the slope.

　　3. Gravity retaining wall: relying on its own gravity to resist soil pressure.

　　4. Pile-board retaining wall: composed of piles and boards, used to support higher slopes.

　　II. Main methods of slope support

　　1. Anchoring technology: by drilling holes in the slope, implanting anchors or anchor cables, and tightly combining them with the slope rock or soil, the stability of the slope is improved.

　　2. Retaining wall: Build a retaining wall at the bottom or middle of the slope to resist the lateral pressure of the soil and prevent the soil from sliding.

　　3. Gabion stone cage: Use metal mesh boxes to fill stones to form a slope protection structure, which is suitable for waterside or eroded slopes.

　　4. Vegetation slope protection: By planting plants such as turf and shrubs, the plant roots are used to reinforce the soil and reduce soil erosion. It is suitable for slopes with smaller slopes.

　　5. Sprayed concrete: Spray concrete on the surface of the slope to form a protective layer, which is suitable for the protection of rock slopes.

　　6. Drainage system: Set up drainage ditches, drainage holes, etc. to remove water from the slope in time and reduce the adverse effects of water on the stability of the slope.

　　III. The main functions of slope support

　　1. Prevent slope collapse and protect the safety of surrounding buildings and personnel.

　　2. Maintain the stability of the slope to ensure the normal progress of the project.

　　3. Reduce soil erosion and protect the environment.

　　Slope support is a complex project that requires comprehensive consideration of geological conditions, engineering requirements, environmental protection and other factors. Reasonable selection of support methods, careful design of construction plans, and strengthening of post-monitoring and maintenance are the keys to ensuring the success of slope support projects. With the development of science and technology, slope support technology is also constantly innovating, providing more effective solutions for engineering safety and environmental protection.
