Abstract: Based on application of U-shape structure automobile passage,which is in Foshan City of Guangdong Province,to wet soft soil foundation,the structure construction and the methods of the soft soil foundation processing of the U-shape are introduced,and the main point about design of the engineering watertightness and drain is given.The calculation model of the U-shape structure in wet soft soil foundation is disacssed and the mechanics characteristics and deformation characteristics of that U-shape structure are analyzed when there is no anti-pulling out pile.Practice proves that the U-shape structure for coastland wet soft soil foundation is applicable,safe,economical and worthy of extending.

Key words: U-shape, elastic foundation, FEA, CFG pile, watertightness
