摘要
抚松县县城至新安村沿江公路山体滑坡,按发生年代为老滑坡,后因人类工程活动在老滑坡的基础上产生了新滑坡。诱发因素主要是降雨、融雪、冻融、岩体自然风化强烈、地表冲沟发育、松散堆积物厚以及人为开挖坡脚,造成滑坡体失稳滑动。目前该滑坡稳定性较差。本文阐述了该滑坡的发育特征、形成机理、稳定性评价,提出防治措施。
The landslides from Fusong County to Yanjiang highway of Xin＇an village, which is old landslide, because of human engineering activities it produced new landslide. Predisposing factors is mainly rainfall, snowmelt, frozen thawing, natural rock weathering strong, surface gully development, loose deposit and artificial excavation slope, which caused the instability of landslide. The stability of the landslide is poor at present. The authors expound the development characteristics, formation mechanism and stability evaluation of the landslide, and put forward the measures for prevention and control of the landslide.
