软弱地基上筒仓桩基设计

Design of Silo Pile Foundation on Soft Ground

结合工程的地质特点、工期要求和筒仓基础的受力和沉降特点等因素,基础采用了预应力混凝土管桩(PHC管桩),通过多方案比较确定了布桩方案,并以该方案为例,介绍了基础设计需要计算的主要内容及其计算参数的选择,重点介绍了竖向承载力、水平承载力以及沉降的计算,最后提出了对施工的要求,可供类似工程参考。

Combined with geological characteristics of a project, schedule requirements and mechanical properties and settlement characteristics of silo basesand, prestressed concrete piles are employed. The pile arrangement is determined through comparison of several proposals. The main contents and analysis parameters during the design of the foundation are introduced by illustration of this project, where calculation of the vertical and horizontal load-carrying capacities and the settlement are intensively described. Finally, the constructional requirements are proposed ,which can be referenced for similar projects.
