摘要
目前．沉管挤密碎石桩已广泛用于加固地基．但在软土地区应用时其复合地基的承载力较低，通过充水预压可使复合地基承载力进一步提高．可拓宽挤密碎石桩的应用范围。结合工程实例说明其加固效果。
At present. the tube sinking compacted gravel pile has been widely used in ground treatment. As for applying it to soft soil area. the bearing capacity of the cornposite foundation is rather low. but can be further increased by water-filling preloading. which may broaden the application scope of compacted gravel pile. The strenthening effect being manifested by engineering practical examples.
