摘　　要：本文结合曹妃甸矿石码头三期工程地基处理,通过试验区的施工及地基处理前后场地高程、标贯击数、液化情况等的对比,着重论述了无填料振冲法在粉细砂中应用的可能性,得出可以指导本地区施工的参数,也为类似工程的设计及施工提供经验。Based on the foundation treatment construction of Caofeidian ore terminal phase-3 project, the practicability of vibroflotation without filling applying to mealy fine sand foundation is emphasized by the comparative analysis on the elevations, SPT blows, liquefaction conditions etc. of the trial zone before and after foundation treatment. And the construction parameters were obtained, which serve as a guide for local projects and a reference for the design and construction of similar projects.

关 键 词：无填料振冲法 粉细砂 吹填土
