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。
Based on the geological characteristics of the project, the requirements of the construction period and the stress and settlement characteristics of the silo foundation, the prestressed concrete pipe pile (PHC pipe pile) is basically adopted, and the pile distribution plan is determined through the comparison of multiple schemes. Taking the scheme as In this paper, the main contents of calculation of basic design and the choice of calculation parameters are introduced. The vertical bearing capacity, horizontal bearing capacity and settlement calculation are introduced emphatically. Finally, the requirements of construction are proposed for reference of similar projects.
