水泥土搅拌桩在滨海地区软基处理中应用研究——以福州滨海新城屿中路软基处理项目为案例

Research on the Application of Cement Deep Mixed Columns to Reinforce Soft Soil Foundation in Coastal Area——a case study of Yuzhong road in Fuzhou Binhai City

针对福州滨海新城软土特点,以新城屿中路某道路工程为案例,论证水泥土搅拌桩在福州滨海地区软土处理中的可行性。随后,反思了水泥土搅拌桩在滨海地区中应用需注意的若干问题,如软土有机质含量、海水中硫酸盐含量、含水量和龄期等。

According to the characteristics of soft soil in Fuzhou Binhai New City,the feasibility of cement soil mixing pile in soft soil treatment of Fuzhou coastal area is demonstrated through the Yuzhong road engineering. Then,some problems that should be paid attention to in the application of cement soil mixing pile in coastal area are discussed,including organic matter content in soft soil,sulfate content in seawater,water content and age.
