Abstract
Through comprehensive using of stereographic projection graphic method,physical scale projection space vector analytical method and block discrete element method,the control effect of different combinations of structural surface and free surface on the stability of high steep slope in rear mountain of Huangjinping Hydropower Station in Dadu River is separately analyzed in this paper.Based on quantitative calculation,the stability coefficient of slope under different conditions and different combination types of structural surface are obtained.Thus,it is shown that the main failure mode is local wedge sliding failure and the most dangerous combination of structural surface as the master control factor of slope stability is J2,J3 combination.关键词
