有效防治旗山滑坡,在主剖面前、中、后位置布设测斜管,进行深部位移监测。位移数据分析结果表明,滑坡演化呈现后缘倾倒拉裂、中部推移剪切和前缘锁固失稳三个阶段,目前处于中部推移剪切阶段,急需滑坡工程治理;主滑面为砂土状强风化岩软弱夹层,目前滑面部分贯通;持续强降雨后深部位移明显,对滑坡稳定影响显著。
Effective prevention and control of Qishan landslide, in the main section of the front, middle and rear of the location of the laying of test tube, the depth of displacement monitoring. Displacement data analysis results show that the landslide evolves in three stages, ie trailing edge tipping and fracturing, middle shear shearing and frontal locking instability, which are currently in the middle of the thrusting and shearing stage and are in urgent need of landslide engineering treatment. The main slip surface is sandy Strong weathered rock weak interbed, the slippery part of the current through; deep deep displacement after heavy rainfall significant impact on the stability of landslides.
