黄莲树滑坡破坏变形机理浅析

Study on Deformation and Failure Mechanism of the Landslide in Huanglianshu

摘要:

以三峡库区奉节县黄莲树滑坡的破坏变形为例，以地表位移、降雨、地下水、库水位的监测为依据，综合分析研究了监测参数的变动和致灾因子相互作用对滑坡稳定性的影响关系，开展破坏变形机理探讨研究，总结形成了初步的研究成果。该研究成果对滑坡的监测预警预报技术具有重要的理论意义，并且对其它以库水位涨落和降雨为主要致滑因子的滑坡的监测临滑预报具有重要的参考价值和指导意义。

Abstract:

Take the example of deformation and failure of landslide in Huanglianshu of Three Gauge and according to the monitoring on ground displacement, rainfall, underground water and the reservoir water level, the effects by the interactions between the changes of monitoring parameters and of hazard factors are analyzed and the deformation and failure mechanism are studied. The paper summed up the preliminary study results which not only has important theoretical significance for monitoring and early warning for landslide, but also has reference value and guiding significance for forecasting just before sliding caused by reservoir water level and rainfall.

Key words:landslide; deformation and failure mechanism; monitoring; reservoir water level; rainfall; landslide of Huanglianshu
