水电工程边坡稳定性研究中应注意的问题

Matters Needing Attention in Study of Slope Stability for a Hydropower Project

文章简述了边坡变形和破坏的原因和过程,以及主要类型及特征。论述对水电工程影响最大的边坡破坏的主要类型,滑坡、崩塌的形成机制、研究调查方法和内容,以及对边坡稳定性的分析评价方法及内容。重点介绍了温度应力匿能新概念,并以瓦依昂滑坡为例,用该概念解释了滑坡失事后未解之谜。从而提出在水电工程边坡稳定性研究计算中应考虑温度应力的影响因素。

This paper gives a brief introduction to the cause, process, type and characteristics of slope deformation and failure, and then expounds the major types of slope failures that have greatest impact on hydropower projects, mechanism of causing landslide and avalanche, contents of study and investigation and their methods, as well as method and contents of slope stability analysis and assessment. The paper puts emphasis on introduction to the new concept of geothermal stress hidden energy, and reveals the mystery of causing landslide by using the concept taking the Wayiang landslide in Italy for example. Thus the paper propeses taking into account the effect factor of geothermal stress in study and calculation of slope stability for a hydropower project.
