振冲碎石桩在海上防波堤工程中的应用

在大连长兴岛北防波堤工程中,采用海上振冲碎石桩技术对细砂液化土层地基进行处理,使其在7度地震设防条件下不液化。文章分析了海上振冲碎石桩施工作业面布置和海上上料工艺等关键点,总结出一套切实可行的施工工艺,并通过碎石桩质量检测结果验证了海上振冲碎石桩施工工艺的可行性。

Application of Vibro-replacement Stone Column on Marine Breakwater Project

The fine sand liquefacient foundation of the north breakwater project of Changxing Island in Dalian adopts vibro-replacement stone column technique in open sea.So that it won＇t be liquidfied under the conditions of 7-degree earthquake fortification.The key point of this passage is to analyze the assignment of vibro-replacement stone column work plane and open sea fill techniques,a set of feasible construct techniques is summed up and the feasibility of vibro-replacement stone column in open sea through stone column quality examination is verified.
