Abstract
This paper proposed a new method of limit equilibrium to solve the 3D slope stability. The method Accordinf to the feometrical features of slide surface,the anfles between the inter-column forces of row direction and horizontal plane and the anfles between the inter-column force of column direction and horizontal plane were equal to a constant. On the basis of three force equilibrium equations and definition of factor of safety, the normal force and shear force actinf on the bottom were expressed by the factor of safety. Then the factor of safety could be calculated by iterative alforithm. Compared with other 3D slope limit equilibrium method,the limit equilibrium slice method considered the interstice force function as much as possible,and met with the needs of each column in 3 direction force balance,as well as the slidinf body around the 3 shaft torque bal-ance,beinf more in line with the actual situation. The calculation results show that,by usinf riforous limit equilibrium method it can obtain stable coefficient of relatively conservative.关键词
