水泥土挤密桩复合基础处理研究

Study on Treatment of Composite Foundation of Soil-Cement Pile

针对湿陷性黄土地质的强度低、易变形的特点,通过采取水泥土挤密桩加固,探究水泥土挤密桩的加固原理,阐述路基处理的施工工序,运用室内实验的检测方法验证复合地基的处理效果。研究结果表明,通过水泥土桩和原地基土所组成的复合地基处理能够改善黄土的物理力学性质,增强抗变形能力。可以对水泥土挤密桩复合基础处理研究提供借鉴。

In view of the characteristics of low intensity and easy deformation of collapsible loess,by adopting cement soil compaction pile reinforcement,study on reinforcement principle of cement soil compaction pile,elaborate the construction procedure of subgrade treatment,verify the treatment effect of composite foundation treatment method with the help of indoor experiment.The results show that the composite foundation formed by cement soil pile and the foundation soil before could improve the physical and mechanical properties of loess and enhance deformation resistance. The paper provides reference for the research on the composite foundation treatment of the soil compacted pile.
