WebThe finite element method (FEM) and the limit equilibrium method (LEM) are commonly used for calculating slope failure risk. However, the FEM needs to carry out post-processing to estimate slope sliding surface, while the LEM requires assumption of the shape and location of the sliding surface in advance. In this paper, an element failure risk method … Webinterface. The maximum axial force at the soil-pipe interface depends on the compaction condition of the surrounding soil and the coefficient of friction between sand and pipeline. In determining the magnitude of the coefficient of friction, the experimental results performed by Brumund and Leonards [3] were used. The test set- small slim christmas trees
