摘　　要：在海门中天地块整理项目建设中,吹填和地基处理工期较短,需要吹填结束后立即进行大面积地基处理。本文结合海门中天地块整理项目,从振冲施工在新近吹填粉细砂场地中的参数选择、质量控制、处理效果等方面,详细分析了无填料振冲在新近吹填粉细砂工况下的适用情况。工程实践表明,无填料振冲法在新近吹填粉细砂工程中地基处理效果良好,可供类似工程借鉴。In the construction of Haimen Zhongtian foundation treatment project,due to short construction period for dredger-filling and foundation treatment,large-area foundation treatment must be carried out immediately after dredger-filling work is completed.Base on the above project,comprehensive analysis is made for the application of vibroflotation without fillings under the condition of newly dredger-filling silty fine sand from the aspects of parameter selection,quality control and treatment effect.Engineering practice shows that the vibroflotation without fillings has good effect,which can be used in similar projects.
