高路堑条件下山区公路边坡稳定性分析及整治方案

Stability Analysis and Treatment Scheme of Highway Slope in Downhill Area Under High Cutting Condition

相较平原地区,山区高速公路坡体结构复杂性更高,且开挖深度较大,遇到降雨等天气极易出现失稳破坏,对工程安全产生不利影响。文中根据某高速公路高路堑边坡施工实践,分析滑坡产生的影响因素,并基于传递系数法分析多种工况条件下边坡稳定性的影响因素,结合项目具体特点制定针对性的处治方案,取得理想的效果。

Compared with the plain area,the slope structure of expressway in mountainous area is more complicated and the excavation depth is larger,which is easy to fail in the event of rainfall and other conditions,which has an adverse impact on the project safety.Based on the construction practice of a highway high cut slope,this paper analyzes the influencing factors of landslide,and analyzes the influencing factors of slope stability under various working conditions based on the transfer coefficient method.According to the specific characteristics of the project,the corresponding treatment plan is formulated,and the ideal effect is achieved.
