路堤下水泥土桩复合地基性状的有限元分析

Finite element analysis of mechanical behaviors of embankment filled with soil and composite ground

结合工程实例,对水泥土搅拌桩复合地基的变形、强度、承载特性、荷载传递、桩土间相互作用等力学性状进行了研究;探讨了桩土模量比、桩长、荷载对桩顶应力的影响,及桩土模量比对桩土中荷载传递规律的影响,得到了具有一定工程价值的结论。

For this kind of composite ground, some basic regularity of deformation, strength, load transferring along depth, interaction between pile and soil, deformation characters, and so on, have been obtained; Debating the influence of module radio,pile length,load and pile top stress, getting some worthy conclusion in engineering.
