公路高边坡稳定性多点位移计监测分析

Monitoring and analysis of mlti-point displacement meter for the stability of highway high slope

公路高边坡地质条件复杂,开挖或支护不当会产生较大的边坡变形,甚至出现滑塌事故。为保证高边坡稳定性,在施工中采用多点位移计对边坡不同深度变形情况进行监测,分析确定边坡变形情况。通过分析多点位移计监测结果,得出路基边坡变形受开挖施工影响最大,确定了滑动面的位置,且完工后路基边坡变形已趋于稳定。

The geological conditions of high road slopes are complex,and improper excavation or support will produce large slope deformations and even landslide accidents.In order to ensure the stability of high slopes,multi-point displacement meters are used in the construction to monitor the slope deformation at different depths,and analyze and determine the slope deformation.By analyzing the monitoring results of multi-point displacement meters,it is concluded that the subgrade slope deformation is most affected by the excavation construction,the position of the sliding surface is determined,and the subgrade slope deformation has stabilized after completion.
