挤密桩法作为湿陷性黄土地区中的一种常见的地基处理方式,对其地基处理效果进行试验分析有着重要的意义。结合某工程开展试验研究,采用室内试验、载荷试验及面波测试等手段,对比分析地基土处理前后的物理力学性质,评价地基处理效果。通过对比分析表明:地基处理范围内完全消除湿陷性,地基承载力满足设计要求。该试验成果在该地区同类工程有一定的借鉴意义。
As a common ground treatment method in collapsible loess area, the compaction pile method is of great significance to the experimental analysis of its foundation treatment effect. Combined with a project to carry out experimental research, using laboratory tests, load tests and surface wave tests and other means, comparative analysis of the physical and mechanical properties of the foundation soil before and after treatment to evaluate the effect of foundation treatment. The comparative analysis shows that the collapsibility of foundation is completely eliminated and the bearing capacity of foundation meets the design requirements. The test results in the region similar projects have some reference.
