| 摘 要： | 长弄屯不稳定斜坡为典型的推移式变形体，特殊的地质结构及演化历史是孕育斜坡变形的内在条件，在降雨和工程开挖耦合作用下，诱发原本不稳定的斜坡产生了推移式蠕滑变形。通过分析评价地质背景、岩土类型、滑体规模、形态结构特征、水文地质条件、岩土物理力学参数等，认为长弄屯滑坡体在天然状态下均处于欠稳定状态，在强降雨天气冲刷下及雨水的入渗作用，滑坡体的自重增加、稳定性变差，滑坡可能进入快速整体滑动阶段，有必要进行工程防护。

| Abstract: | The unstable slope in Changnongtun is a typical slide deformation body.The special geological structure and evolution history are the internal conditions of the slope deformation.Under the coupling action of rainfall and engineering excavation,the slide creep deformation of the originally unstable slope was induced.Through analysis and evaluation of geological background,rock and soil type,sliding mass scale,morphological and structural characteristics,hydrogeological conditions，rock and soil physical and mechanical parameters，etc.It was considered that the Changnongtun landslide mass is in an unstable state under natural conditions.Under the scouring of heavy rainfall weather and the infiltration of rainwater,the self weight of the landslide mass increases and the stability becomes worse.The landslide may enter the rapid overall sliding stage,so it is necessary to carry out engineering protection. |
