| 摘 要： | 以ANSYS为计算工具对一粉喷桩复合地基实际工程进行方案优化计算,在合理建立复合地基有限元模型的基础上,通过设定桩长、桩距为设计变量,复合地基承载力、平均竖向位移为状态变量,粉喷桩工程量为目标函数构建了粉喷桩复合地基的优化体系,研究了基于ANSYS的粉喷桩设计方案优化方法,得到了平均沉降随桩长、桩距的变化情况及本工程条件下的粉喷桩复合地基优化组合。

| Abstract: | According to a real dry jet pile composition foundation project,ANSYS software was used to optimize the design.A reasonable finite element model was established.Through setting the length of pile and the distance of piles as variables for design,the bearing capacity and vertical displacement as state variables,the engineering work load of pile as objection function,the optimizing system established.In this paper,optimizing method,based on ANSYS,of dry jet pile composition foundation was studied.At the same time,the rule of average settlement vary with the length of pile and distance of piles as wall as the optimizing design of the project were got. |
