摘要
长短桩复合地基自使用以来,由于其在地基的处理中能降低工程造价,能较好的减少地基沉降,从而一直被广泛应用于土木工程建设中.主要从长桩桩长变化以及短桩桩长变化入手,应用ABAQUS三维有限元处理软件,分析桩长变化对复合地基基础沉降的影响.通过分析,可以得出在地基处理中,由于长桩长度的增加可以有效的减小地基沉降,从短桩的角度来看,不仅可以减小工程造价,而且可以最大限度的减小施工难度.
The using of the long-short pile composite foundation can reduce the engineering cost and foundation subsidence, so it is widely used in engineering. This paper uses finite element software ABAQUS to analyze the influence of pile length change on the foundation settlement based on the change of long pile and short pile. The conclusion is drawn by the analysis that long pile can reduce the foundation settlement and short pile can reduce the construction cost and minimize the difficulty with a large margin.
