摘要 世寿街滑坡位于沱江下游河口段右岸。形成的主要因素是斜坡体内广布极易滑的粉质粘性土层、江水周期性的浸泡、冲刷、以及人为加载和生产、生活活动。呈现牵引—推动的复合发生机理。由于滑坡区为综合房地产开发之用 ,滑坡防治不仅要考虑滑坡本身的稳定 ,而且还要考虑滑体上各种建筑物的安全运行。采取了主要因素控制法。 Shishuojie landslide is located on the right bank of bayou of lower reaches of Tuojiang River. Its volume is about 10.32×10 4m 3. The main factors for the formation of the landslide are the periodic soaking & washing of silt clay in the slope by river and artificial loading production and living activities. The mechanism for the landslide ouucrrence appears to be composite draught and push. The process of slide can be divided into three stages: the reduction of clay strength in slip zone, and the shifting of landslide baby composite stress from back to front, and integer slide. According to the groundwater regime, a statics model is set up to estimate the landslide stability. In control on the landslide we must conside not only the stability of landslide but also the safe operation of buildings and then take the measures against the main factors.
