Study on the Determination Method and Influence Factors of m Value Based on Nonlinear Finite Element Analysis

Abstract

The determining of m value in “m” method has great significance to force analysis of pile foundation buried segments. In this paper, a finite element software is used for the nonlinear finite element analysis of elastic long pile under the horizontal force action, and combined with the related provisions and formulas for “m” method given in 《Code for Pile Foundation of Harbour Engineering》, a accurate m value can be obtained conveniently. Then based on this method and by the single factor analysis, a more systematic study was made to the related factors, and obtained the influence law of various factors to m value.
