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

The stability evaluation on superhigh slope behind the powerhouse of Geheyan hydroelectric station over Qingjiang River is made in this paper. Engineering geological condition, new tectonic movement, and deformation observation results for the slope are analyzed. 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.
