福州官头码头位于福州闽江口北岸 ,整个驳岸、堆场和道路下方有 7～2 3ｍ厚淤泥及淤泥质粘土。该层土质差 ,地基无法满足使用时 112ｋＰａ承载力和变形要求 ,须进行人工处理。经比选 ,采用水泥搅拌法来加固。搅拌桩断面呈双轴“8”字形 ,深度 8～ 2 3ｍ。经南京水科院土工所室 Fuzhou Guantou Ferry Terminal is located on the north bank of the Minjiang River estuary in Fuzhou. There are 7 ~ 23m thick silt and silt clay under the entire dock, yard and road. This layer of soil is poor, the foundation can not meet the use of 112kPa bearing capacity and deformation requirements, to be carried out manually. After comparison, using cement mixing method to reinforce. Mixing pile section biaxial “8” shape, the depth of 8 ~ 23m. Nanjing Institute of Hydrology by the geotechnical room
