摘　　要：国外某大型燃煤电站取水泵房位于海边红树林滩涂的软弱土层上,泵房下部采用预制沉井结构,软基处理采用混凝土灌注桩方案,结合施工方案,对泵房施工期和运行期的沉井结构分别进行设计优化,控制下沉方式和下沉系数,并对沉井泵房桩基与沉井施工次序进行优选,针对工程特点,结合工程实际,简述带桩基的沉井结构泵房设计要点,为同类工程设计提供参考。A water intake pump station of a coal-fired power plant is located on the seaside mangrove with soft soil subgrade.The lower part of the pump station adopts a prefabricated caisson structure with pile foundation.Combined with the construction scheme,this article optimized the caisson structure design during the construction phase and operation phase of the pump station,and optimized the construction order of the pile foundation and the caisson sinking construction.According to the actual engineering situation,the design key points of the caisson pump station with pile foundation are briefly described,which provides a reference for the design of similar projects.
