摘要
本文结合实地调查，认为鄂西南切蚀型滑坡，以人工切蚀为主要触发因素，自身重力和降雨引起滑面土体软化、孔隙水压力的联合作用为致滑机理，并集中发育在暴雨中心的水电工程、公路和城乡基本建设等人类工程经济活动区。
Combined with in-situ investigation, this paper considered that man-made cutting erosion is the main trigger factor of landlids while the sliding mechanism contributed by the combining effect of soft slide plane soil and pore water pressure which induced by selfweight and softened by rain water. It concentrate in districts with strong human activities such as hydroelectric engineering, road engineering and city or country constructions among rainstorm centre. It also explained the surfacial character induced by towed slide and the prevention coutermeasures of them.
