摘要
提出了桩承式复合地基的基本概念和适用范围,并推导了初步设计方案的理论式;在此基础上,以电厂中平均堆载达220k Pa的圆形煤场为例,通过对试验区有限元模型分析和物理试验的结果比较对照,提出了应用非线性有限元详细计算桩承式复合地基的方法。
The concept and application range of pile-supported composite ground were presented,and the theoretical formula for preliminary design scheme was deduced.Based on the background of the design of round coal field with220 kPa bearing capacity of soil,the load test of pile-supported composite ground was done to compare with finite element method calculation.Based on the results of comparison,the detail analysis method for nonlinear finite element method was modified and presented to solve the design problem of pile-supported composite ground.
