Abstract

Abstract

Slope angles and strengths are important factors influencing slope stability, while slope instability is often accompanied with large deformation, ranging from tens to thousands of meters. For traditional finite element methods, calculation often terminates due to grid distortion in the large deformation cases. The finite element method with Lagrangian integral points (FEMLIP) was adopted to simulate the large deformation landslide process of slopes and study the effects of slope angles and strengths on slope stability. The C language was used for the Ellipsis programming to simulate the whole process of slope instability and collapse, which was verified with a typical case. The stability and landslide processes of the slope under different slope angles and strengths were analyzed with this method. The results show that, the FEMLIP can accurately find out the potential slip surface of the slope and simulate the landslide development process after the slope instability, making a new numerical way for the large deformation analysis of the slope landslide.
