填土路堤下复合地基受力与变形的CAT分析

CAT Analysis of Properties of Embankment Composite Foundation

本文利用编制的二维有限元程序,分析了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影响,特别是路堤刚度变化对应力比的影响,并模拟了填土路堤下复合地基的受力性状,从而为填土路堤下复合地基的设计提供了参考依据。

This paper analyzes the impact of pile and soil modular ratio, replacing ratio, pile length and embankment modular on ground settlement, lateral deformation and stress distribution, especially impact of embankment rigidity on stress ratio. Furthermore , behaviour of embankment composite foundation is simulated and reference material for its design has been supported.
