条基宽度对条基-疏桩承载性能影响的数值模拟

条基—疏桩是一种新兴的基础形式 ,其推广应用也取得了一定的经济效益和社会效益。工程设计中需要确定合理的条基宽度 ,本文通过ANSYS数值模拟的方法 ,计算了薄软土层条件下条基宽度在 0 .5 - 3.0m范围内变化对条基—疏桩承载性能的影响 ,为条基宽度的设计优化提供了参考

The numerical simulation of raft widthon sparse pile compound foundation

Raft sparse pile is a new pile foundation which has applied to some area. The Sparse Compound Pile has fully developed the bearing performance of pile and raft. There are many factors affecting the sparse compound pile foundation's bearing performance, In the project design, the width of raft needed to be optimized which is an important factor. The application of the foundation has gain some economic profit and some social profit.Though the numerical method of ANSYS,calculating the effection of the raft width ranging from 0.5 to 3.0 m on bearing performance of raft sparse pile in the condition of thin soft soil ground.This paper gives a good reference on the design of raft sparse pile foundation.
