摘要

利用野外地质调查与钻探等手段,查明了窑淮乡滑坡所处的地质地理环境及滑坡的基本特征,利用室内试验、工程地质类比、反演分析等手段综合确定滑带土的抗剪强度参数,选取典型主滑剖面进行稳定性分析。结果表明:滑坡体在天然条件下,整体上处于蠕滑状态,其稳定系数小于安全系数,处于欠稳定状态;在暴雨工况和地震工况条件下,稳定系数均小于1.0,处于不稳定状态,建议及时对滑坡进行治理。
The geological environment and basic characteristics of landslide in Fangxian was invested by using field geology survey and drilling,the shear strength parameter of soil in slide zone was obtained by using laboratory test,engineering geological analogy and inversion analysis,then the stability of typical cross section of landslide was analyzed.Results showed that under the natural condition,the slope is on creeping state and its stability coefficient is lower safety coefficient,which is lack of stability state;under the heavy rain and seismic conditions,its stability coefficient is lower 1.0,which is on unstable state and should be treated.
