Stability analysis of rock high slope and study on prevention and control measures
摘要
Abstract
The stability of rock slope is one of the most prominent geotechnical problems in hydro project area,and the evaluation of rock slope stability is of great significance.The control structural plane is concluded based on sta-tistical analysis of the dominant structural plane,which is an effective method to evaluate the stability of rock slope with complex structure.Taking the high slope by the lower approach channel of the ship lock of Yangxi Hydraulic Complex as example,the control structural plane of the slope is obtained through the comprehensive evaluation by horizontal projection technology and limit equilibrium method,and corresponding supporting measures are put for-ward.Under the action of control structural plane,the potential instability mode of the slope is wedge mode.After a comprehensive consideration of the rainstorm condition and flood season condition,it is concluded that rainstorm condition has the greatest influence on slope stability.The support measures proposed for the slope are evaluated comprehensively,which confirms the effectiveness of the support measures.关键词
