摘要
莫洛村滑坡由多期泥石流堆积形成,虽然滑坡体的坡面和滑面都比较平缓,但滑坡体良好的汇水条件和地下水流动产生的动水压力是滑坡变形发展的重要因素。根据成因的不同,莫洛村滑坡可划分为两个滑坡,#1滑坡是由降雨诱发的推移式滑坡,处治的关键在于将地下水拦截并排出滑坡体外,#2滑坡是由河水冲刷掏蚀导致的牵引式滑坡,需设置防冲墙防护。实施治理后,已经稳定。
Moluocun Landslide comes from multi-stage accumulations of debris flow. Although the landslide has relatively gentle slope and sliding face, the dynamic water pressure arising out of the good catchment condition of the landslide and the underground water flow is an important factor of the landslide deformation development. Based on the different geneses, Moluoeun Landslide may be divided into two landslides, wherein the Landslide 1 is a thrust load caused landslide induced by rainfall with the key to treatment lying on interception and drainage of underground water out of the landslide; the Landslide 2 is a regressive landslide caused by river souring and erosion, and required to be protected by setting anti-scour wall. It is stable now after treated.
