| 摘 要： | 借鉴砂井法加固粘性土地基的机理, 提出了用强夯砂土桩法加固饱和粉质粘土地基, 对某工程试夯区进行的现场试验表明,不仅砂土桩本身密实性好、强度高, 而且桩间土的物理力学性能也得到了很好的改善, 复合地基承载力得到了大幅提高。工程应用结果也证实加固效果显著。

| Abstract: | Drawing the experiences of mechanism of reinforcing
clay-soil foundation in the sand drain method, the present paper puts forward a method in
which the saturated silty clay foundation is reinforced by dynamical sand-soil piles.
Loading testing research on proving zone of a practical project has showed that not only
the sand piles have high density and strength, but also have physical and mechanical
properties of ground soil been significantly improved. Bearing capacity of composite
ground has been greatly enhanced. Application of the method to the project also proves the
testing results. |
