| 摘 要： | 本文结合我省首次采用沉管挤密碎石桩加固一多层住宅小区粘质粉土地基的工程实践，通过对碎石桩成桩后不同时段进行的桩间土静力触探、复合地基表面波速法试验以及加固前后地基的静荷载等试验，对挤密碎石桩加固粘质粉土地基的机理进行了探索，并通过分析，提出了一些可供工程设计及施工的参考建议。

| Abstract: | In consideration of the case of using pipe sinking gravel compaction piles method for improv-ing clayey si1t, static penetration tests, surface wave field tests, loading plate tests as well asmoisture content tests were carried out for such soil at different stages after the improvement.From the results of these tests and analyses, suggestions for practical design and construction arepresented in this paper. |
