Comparison of simulated behavior of pile for landslide by FEM and dowel pile formula

Abstract

To clarify the applicable conditions of the design formula of landslide pile from a modulus of deformation of landslide soil mass and pile bending stiffness, sensitivity analysis by the finite element analysis using the model slope which is changed by modulus of deformation of landslide soil mass, the pile bending stiffness and the piling position was carried. As a result of analysis, When β-lwhich is calculated by modulus of deformation of landslide soil mass and the pile bending stiffness become three or less, the moment obtained by finite element analysis become bigger than the moment obtained by long pile formula and finite length pile formula of the dowel pile.
