某输气管线760~#滑坡形成机制及稳定性分析
|
摘要
通过区域地质调查,大比例尺平面图测绘,滑坡微地貌和变形破坏特征测量等手段,对某滑坡的特征和形成机制进行了系统研究。在认识滑坡形成机制的基础上,采用多种极限平衡计算方法,并结合滑坡所处的地质环境,评价该滑坡在天然、降雨、地震以及降雨和地震耦合作用下的稳定性,为该滑坡的治理提供理论指导。
A systematic research on characteristics and forming mechanism of 760# landslide at a Oil Transporting Pipelines was achieved in terms of such methods as regional geological investigation,large scale topographical map measurement of micro-physiognomy and failure and geophysical reconnaissance survey.Based on landslide's forming mechanism,the stability of state was evaluated by various limit equilibrium methods.Combining geological environment where landslide located on effects of natural state,or rainfall,or earthquake,or rainfall and earthquake.The research result can take a theoretic guide rule in the landside treatment.
