清江隔河岩电站厂房超高边坡的稳定性评价

Stability Evaluation on superhigh Slope Behind Powerhouse of Geheyan Hydroelectric Station, Qingjiang River

本文从该边坡的工程地质条件、区内新构造运动、坡体变形特征的观测;自然边坡角,稳定边坡角与设计边坡角的关系;极限平衡稳定计算分析及有限元分析等方面来评价它的稳定性,并提出了防滑措施。

The stability evaluation on superhigh slope behind the powerhouse of Geheyan hydroelectric station over Qingjiang River is made in this paper. Engineering geological con dition, new tectonic movemet, and deformation observation results for the slope are analized. Natural angles, stable angles, and design angles of the slope are compared with each other. Limit equilibrium analysis and finite element method are used for the stability evaluation of this slope. The engineering prevention and cure of landslip hazards are also proposed in this paper.
