An improved method of 3D loess-slope stability calculation under the effect of earthquake

ZHANG Jian-bo①,SUN Jing①,LAN Xiao-wen②(①Faculty of Information Engineering,China University of Geosciences,Wuhan 430074,China;②Institute of Crustal Dynamics,China Earthquake Administration,Beijing 100085,China)  
Loess landslide occurrs seriously,especially under the effect of the loess texture and earthquake.Due to the inadequacies of the 2D slope stability calculations,this paper proposed a 3D analysis method in the establishment of an improved 3D loess-slope model.The feasibility of the analysis method was verified by theory and practice.The experimental results showd that 3D calculation method could be not only more accurate and effective,but also more practical.
