粉喷桩复合地基力学性状的数值分析

The numerical analysis of mechanical property of cement injection pile composite foundation

把路堤假设为一个柔性荷载和一具有较小刚度的垫层,应用FLAC2D数值分析软件,选择一工程实例,对水泥土搅拌桩复合地基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和理论意义的结论。

The embankment was supposed as a flexible loading and bedding cushion with litter rigidity,with FLAC2D numerical analysis software,an engineering example was chose,the mechanical property of cement mixed composite foundation was studied.The pile soil modular ration,pile length and loading influences on pile prestress and pile soil loading delivery law were discussed.Some conclusion with some engineering value and theoretical meaning were obtained.
