特大黄土滑坡事故责任认定中的岩土力学问题

在滑坡影响因素研究的基础上，采用极限平衡和数值模拟的方法分析了西部某矿山特大黄土滑坡灾害的发生机理，认为此次滑坡是在断层和地下开采等不利条件下，由大气集中降水诱发黄土湿陷形成的推移式滑坡，与管线漏水形成的“过湿带”不构成直接因果关系，为事故责任认定，解决矛盾纠纷提供了理论依据。

Problems of rock-soil mechanics on responsibility cognizance of great loess landslide

Based on the study of influencing factor of landslide, the limiting equilibrium method and numerical simulation method were used to analysis the evolutive mechanism of a Great Loess Landslide, which happened in some mine in west China. It was reckoned as a driving mode landslide, affected by the disadvantages of fault and underground mining, caused by a mass of rainfall and the water-collapse character of loess, and had no direct relationship with the ＇ over-wet zone＇ engendered by the pipe leaking. It provides technical referrence for responsibility cognizance of the landslide disaster and the solution of conflict.
