| 摘 要： | 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。

| Abstract: | To control the landslide,its depth displacement was monitored with inclinometer tubes at the front,middle and back of the main section.The analysis of the data shows its evolution consists of posterior toppling-fracturing,middle pushing-shearing and anterior backup-failing stages.It is currently in the middle stage,needing urgent engineering treatment.The main sliding surface is sand-like intensely-weathered soft interlayer and some sliding surfaces are connected.Heavy rainfalls have an obvious effect on displacement and stability. |
