摘要
利用弹性、Duncan-Chang非弹性两种本构模型 ,将平面问题有限元法用于填土路堤下复合地基性状的研究 ,对复合地基中的桩土刚度比、置换率、桩长以及路堤刚度等对地基沉降、侧移及桩土应力分配的计算结果进行比较。
Using linear elastic and non linear elastic (Duncan Chang model) constitutive model and plane problem finite element method in the study of properties for embankment composite foundation,we will analyze how pile and soil modular ratio,replacing ratio, pile length and embankment modular influence setting of ground,lateral deformation and stress ratio. Furthermore,behavior of embankment composite foundation is simulated and reference material for its design has been supported.
