山区公路建设中出现了大量的高切坡,其稳定性对整个工程的意义重大。以重庆一山区公路改建中的高切坡工程为例,从地质、地貌、水文和人为因素等多方面分析了其发生失稳变形的原因,在此基础上,采取工程措施对高切坡进行了加固处治。处治效果表明,对高切坡失稳变形原因的分析和工程加固措施的选择均是合理的。 There have been a lot of high cut slopes in the construction of mountainous roads, and their stability is of great significance to the whole project. Taking the high cut slope project in the reconstruction of a mountainous area of ​​Chongqing as an example, this paper analyzes the causes of instability deformation from the aspects of geology, geomorphology, hydrology and human factors, and on this basis, takes engineering measures to conduct the high cut slope Reinforcement treatment. The treatment effect shows that it is reasonable to analyze the causes of the instability deformation of high cutting slope and the selection of engineering reinforcement measures.
