pyBIMstab: Application software for 2D slope stability analysis of block-in-matrix and homogeneous materials

Abstract

We present the application software, pyBIMstab, which evaluates the factor of safety (FS) against sliding of slopes made of either blocks-in-matrix (bimsoil∖bimrock) taking into account the tortuosity of failure surface or homogeneous materials with typical circularly-shaped surfaces. In the case of tortuous surfaces, they are found with the optimum pathfinding algorithm named A∗(A star). Keywords: Tortuous failure surface, Bimrock, Bimsoil, Slope stability, A∗algorithm
