首先对振冲碎石桩法在不同土质地基中的加固机理进行了阐述;然后,以实际工程为依托,对应用振冲碎石桩法处理高液限软粘土地基的施工、加固效果检测等方面的问题进行了讨论。对于高液限的软粘土地基,常规的排水固结方法很难得到预期的效果,采用振冲碎石桩法,形成复合地基,可以较好地解决高液限软土地基的加固问题。

Discussions were first made on the mechanism of vibro-replacement crushed stone columns for different types of soils and then, based on the experience on a practical project, methods for building vibro-replacement crushed stone columns for improvement of soft soils and methods for testing to verify the improvement effect of the vibro-replacement crushed stone columns were also discussed. For soft soils with high liquid limit, ordinary methods of consolidation of soil by dewatering have proved to be hardly effective and now the problem can be solved by using vibro-replacement crushed stone columns to form a composite foundation.
