| 摘 要： | 本文用Ansys分析了多支盘水泥土桩复合地基中的桩体应力、桩间土应力和位移,总结了多支盘水泥土桩的承载特性:设置多支盘,承载力增加约40%,桩侧受力约占90%,第一个支盘受力最大,承载力随盘数、盘径、盘距、桩体弹性模量等产生变化。并分析了多支盘桩的弹性模量、盘数、盘径对复合地基变形的影响。

| Abstract: | In this paper,the author analyzes on pile-stress,stress of soils between piles and displacement of piles using Ansys.The conclusion is that the bearing capacity is increased by 40% with branches,pile-side friction is about 90% of single-pile bearing capacity,first branch bears most loads,bearing capacity varies with the numbers of branches,diameters of branches,intervals of branches and elastic modulus of piles.Elastic modulus,number of branches and diameters of branches affect deformation of branch-cement-pile composite foundation. |
