湿软土基地段U型槽式结构应用技术

Application Technique of U-Shape Structure to Wet Soft Soil Foundation

以广东佛山市某一U型槽式结构在湿软土基地段应用为背景,介绍该U型槽结构构造及软基处理方式,给出该工程防排水的设计要点,探讨湿软土地基U型槽结构的计算模型,分析不设置抗拔桩时U型槽结构的受力和变形特点.实践表明,U型槽式结构对于沿海湿软土基地段是适用的、安全的、经济的,值得推广.

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.
