| 摘 要： | 针对关于弱排水柱复合地基固结性状的研究还处于初步阶段的情况,采用水泥土搅拌桩为研究对象,对其进行了探讨。利用有限元计算对弱排水桩复合地基孔压消散的规律进行了分析与研究,得出了极端处孔压随时间的变化规律,以及不同荷载作用下的孔压分布情况,并通过实测结果得到了进一步验证。据此提出了若干建议性的结论,为解决复合地基固结性状问题提供了一定的理论指导。

| Abstract: | Based on consolidation behavior of weak drainage-pile composite subgrade in an original phrase,the authors discuss it by taking cement-soil mixing piles for studied object.On the basis of actual project,the authors analyze and study the law of pore pressure dissipation in weak drainage-pile composite subgrade by using finite element calculation,and enduce the law of pore pressure with time in pile-bottom soils and the distribution of pore pressure under different loads,which is validated by actual observation results,then made some suggestions in this paper,which gives some theory guidance to settle the problems of consolidation behavior of composite subgrade. |
