摘要
以水泥土搅拌桩复合地基静载荷试验为原型,采用FLAC3D计算不同桩径和桩距复合地基的承载力和桩土应力,得到了改变桩径和桩距对承载力、复合地基沉降以及桩土应力比的影响,对改变桩径和桩距两种方案进行比较,为水泥土搅拌桩复合地基的设计提供了参考。
Based on static load tests of cement-soil piles composite foundation, the supporting capacity of composite foundation and pile-soil stress ratio with various pile diameters and pile spacing were calculated with FLAC3D. The influence of pile diameter and pile spacing on supporting capacity and settlement of composite foundation and pile-soil stress ratio in composite foundation are obtained. By comparing two plans, advices are offered in designing cement-soil piles composite foundation.
