摘要
岩石高边坡通常具有复杂的地质结构和变形破坏机理,其变形与失稳破坏是一个复杂的地质力学过程。本文以相似原理为基础,采用底摩擦试验的方法深入研究了锦屏一级水电站左岸坝肩边坡的变形破坏模式,探索边坡变形与工程开挖的内在联系。试验结果为该水电工程左岸坝肩边坡稳定性分析提供重要理论依据,对工程施工具有一定的指导意义。
The deformation and failure of high rock-slope is complex in geological-mechanics process because of the geological structure and deformation-destruction mechanism of the slope. This article researches the deformation-destruction mechanism and intrinsic relationship between deformation and excavation of the slope at left abutment of Jinping first stage hydropower sta- tion through experiments of basal contacting friction based on the principal of similitude. Results of experiment provides the im- portant theory basis for the stability analysis on the slope. It also has instruction to the project construction.
