地震对边斜坡稳定性的影响研究

Study on Earthquake Effect of Margin Slope Stability

地震作为一种突发式的自然灾害,对边斜坡稳定性的影响是显著的,因此研究边斜坡稳定性在地震动力作用下的变形、破坏具有重要的理论和现实意义。笔者在总结了地震边斜坡稳定性常用的分析方法的基础上,提出了刚体极限平衡法中地震力的确定方法及考虑地震力作用的计算模式,为地震边斜坡的稳定性评价提供了途径,为该类项目防治工程设计提供了科学的依据,值得同类工程借鉴和推广。

As a sudden natural disaster, earthquake has remarkable impact on the margins of slope stability. Therefore, the study of margin slope stability in the deformation and destruction of the earthquake dynamics has important theoretical and practical significance. Based on the common analysis methods of earthquake margin slope stability, this paper puts forward a way to determine the earthquake power with rigid body balance limit law and a calculation model to take into consideration of the role of earthquake power. They provide a channel for the assessment of seismic margin slope stability and a scientific basis for the en- gineering design of similar projects.
