摘要
应用振冲碎石桩加固软土地基和砂基地，可增强抗震稳定性，提高承载力和减少沉降量。同时该工艺具有施工简便、工效高、成本低和效益显著的特点，给大面积的水利工程地基加固处理提供了有利条件。
The soft soil and sand foundation consolidated by vibration and impaction stone column can strengthen earthquake- resistant stability, raise bearing capacity and reduce settlement. This technology has some characters of simple contruction, high efficiency, low cost and good benefit, provides condition for its generalization in water project foundation consolidation.
