云南丫堵新寨滑坡稳定性分析

摘要

Yaduxinzhai landslide is threating the property and life of dozens of people's.Thus,it is necessary to investigate the geological structure and analyze slope stability.Based on field geological drilling,the stability coefficient of landslide is calculated by limit equilibrium theory.The slope is in a stable state as a whole.Landslide H in the conditions of a condition, the landslide is in the less stable state;the landslide is in an unstable state under conditions of two conditions;the landslide is in an un-derdeveloped state under the conditions of three conditions.The stability coefficient of landslide under rainfall condition is significantly reduced,and there is the possibility of sliding instability.%丫堵新寨滑坡威胁坡底数 十户居民的生命财产安全,因此对该坡体进行地 质结构调查和 稳定性研究 十分必要.基于现 场 地 质钻探,采用极限平衡理论计算滑坡的稳定系数.斜坡整体处于稳定状态,滑坡H在工 况一条件下,滑坡处于欠稳定状态,工 况二条件下,滑坡处于不稳定状态,工 况三条件下,滑坡处于欠稳定状态.降雨条件下 滑坡稳定性系数 出现 显著降低,存在滑动 失稳的可能.
