摘要
华北地区某煤炭码头是目前国内正在施工最大的筑港项目,大部分区域上部土层以新近吹填松散粉细砂为主,部分浅层夹淤泥质土夹层。施工中对不同的地基采用不同的加固工艺,对新近吹填砂形成的陆域,主要采用不加填料的振冲联合强夯碾压的软土地基处理方法。处理后经检测,满足设计要求,取得了较好的社会和经济效益。
A coal wharf in North China is the largest port building project under construction in China.The upper soil layer in most areas is mainly newly hydraulic reclamation loose silty fine sand,and some shallow layers are mixed with muddy soil interlayer.Different reinforcement processes are adopted for different foundations during construction.For the land area newly formed by hydraulic reclamation sand,the soft soil foundation treatment method of vibroflotation combined with dynamic compaction without filler is mainly adopted.The test shows that it meets the design requirements and achieves good social and economic benefits.
