摘要
移民新区东坡滑坡发育于小吉尔格朗河东岸二级残留阶地,坡面中部,坡体平均坡度35°,均为小型土质滑坡。因滑坡剪出口位置较高,滑动后,多为快速滑动,极易成灾,对沙尕村移民新区构成较大威胁。通过研究发现,滑坡主要受地形地貌、地层岩性、地质构造等原生地质条件控制,受大气降水、地下水、地震、人类工程活动等外界条件影响,其中大气降水和地下水为滑坡成因的主要影响因素。结合滑坡成因及影响因素,提出抗滑桩板墙和挡土墙相结合并辅以排水措施的防治方案,对该地区的滑坡防治具有较好的指导意义。
The landslide of the new immigration in the mid slope of Jier Gelang River are small-scale soil landslide,the slope gradient is 35°.Due to higher export landslide cut posi-tion,the landslide is a greater threat of saga village.The research shows that landslides mainly due to topography,lithology,geological structure of native geological conditions con-trolled by atmospheric precipitation,groundwater,earthquakes,human activity and other external conditions,including precipitation and groundwater as the main factors Landslide Causes .Landslide Causes and Effects of combination of factors put forward anti-slide Piles and retaining walls combining prevention programs and supplemented by drainage measures, with good guidance for the landslide control area.
