摘要
用振冲碎石柱法在滨海地区平整场地土岩组合地基上一次的成功实践，其场地下伏基岩单向坡度约为２５％，通过合理地选用碎石桩布置、施工方案及建筑结构措施，实现了复杂地质条件下的地基处理，满足了建筑物对地基承载力和变形的要求，并且解决了在地震作用下地基土的抗滑稳定性问题。
A successful practice of vibrofloatation for improving flat ground base is presented. The base is composed of soil and weathered rock stratum in coastal area. The surface slope of underground weathered rock is about 25%. By means of rational layout of stone piles and special plan of construction, the ground treatment has been accomplished to meet the building's demands not only for bearing capacity and deformation limitation but also for anti-sliding stability of ground base under seismic action.
