摘要
为深入分析绵阳高家梁山东侧2#滑坡的稳定性变化特征,基于现场调查资料以及勘测信息,选取该滑坡三个典型剖面进行稳定性评价,考虑了自然工况、暴雨工况、地震工况以及暴雨+地震工况下,滑坡体的稳定性变化特征。结果表明,自然工况下的滑坡属于稳定状态,但在暴雨工况以及暴雨+地震工况条件下,滑坡属于欠稳定状态。
In order to deeply analyze the stability variation characteristics of No.2 landslide on the east side of Gaojialiang mountain in Mianyang,based on the field investigation data and survey information,three typical sections of the landslide are selected for stability evaluation.The stability variation characteristics of the landslide under natural conditions,rainstorm conditions,seismic conditions and rainstorm+seismic conditions are considered.The results show that the landslide under natural conditions is stable,but under rainstorm conditions and rainstorm+earthquake conditions,the landslide is unstable.
