水泥土搅拌桩地基处理中桩长桩间距非线性有限元分析

水泥土桩在增加地基强度、提高地基承载力、减少土体压缩变形等方而效果显著，近年来逐渐得到广泛应用，水泥土桩的复合地基相应的理论研究工作却远落后于实践，利用ANSYS非线性有限元的方法分析水泥土桩地基处理中对桩长和桩间距对加固层和下卧层应力的影响，加固层和下卧层沉降的影响参数影响。得出了合理控制设计水泥土桩的应力的一些结论。

Analysis on Non-linear Element between Middle and Long Poles in Treatment of Soil Foundation for Concrete Poles

The concrete pole produces remarkable result which can make strong capacity if ground foundation, improve the bearing capacity and reduce the deformation which soil is compressed. This technique has been widely applied gradually. It is, however, the relative theoretical research work with compound of concrete and earth pole has for legged behind the practice. This paper with the non-linear limited element means of ANSYS, analyzes the stress influence to the bottom layer and reinforced layer VS the length of concrete pole and distance between poles in treatment of earth foundation. It also analyzes the impact of reinforced layer and the subside of bottom layer and their parameters. It made the conclusion for the stress of reasonable controlling design for concrete poles.
