Study on the Key Points of Slope Reinforcement in Mountain Geotechnical Engineering

Abstract

Slope instability in mountain geotechnical engineering can cause great damage to the engineering structure and the surrounding environment. Therefore, it is necessary to strengthen the slope to meet the demand of environmental safety. This paper firstly analyzes the main reasons of slope instability. Then, through the analysis of the existing research results, four common slope strengthening technologies and their advantages, disadvantages and application ranges are obtained. Finally, taking the slope reinforcement of Jiazhaerjia Cave Mural protection project as an example, this paper studies the reason of using anchor cable ground beam and anchor point reinforcement method and calculates the reinforcement effect after using this method. Through the analysis, it can be found that the environment should be studied before the slope reinforcement, and the matching reinforcement method should be selected through the environment. In the slope reinforcement of Jiazhaerjia Cave Mural protection project, the rock mass is broken and easy to collapse, and the reinforcement method requires less disturbance to the mountain. Therefore, the method of anchor cable ground beam and anchor point reinforcement has the best effect. This paper can provide theoretical and practical reference for mountain geotechnical engineering slope reinforcement.
