营运公路路堑滑坡成因、治理研究及监测措施分析

Analysis on the Causes, Treatment and Monitoring Measures of Slope Landslide on Operational Highway

营运公路边坡滑坡变形危害较大,影响运营公路行车安全。通过现场勘查,结合现场变形情况,对滑坡的工程地质条件进行了分析;将滑坡边坡划分为三个分区,对各滑坡分区的滑动面以及稳定性进行分析,评估各分区的安全。根据各分区变形特征,对各滑坡分区采取不同处治加固措施,提出相关监测建议,可为广东省内其它类似营运路堑滑坡治理提供借鉴。

The slope-landslide deformation of operational highway has a serious bad influence on the operation safety.This paper analyzed the engineering geological condition of slope landslide based on scene investigation of the deformation data.The sliding slopes were divided into three partitions,whose sliding-slip surface and stability was analyzed to assess the safety of the partitions.According to the deformation characteristics of each partition,different treatment measure was taken on different landslide with correlated monitoring suggestion,which provides some references for the landslide treatment of operational highway in Guangdong Province.
