高层建筑桩-箱基础设计浅析

PRELIMINARY ANALYSIS ON DESIGN OF PILE BOX FOUNDATION FOR A HIGH MULTI STOREY BUILDING

结合上海武警指挥学校综合办公楼工程实例， 采用桩－箱基础， 在箱形基础下加桩， 以满足加强承载力和防止变形要求。桩－箱基础系由底板、顶板外墙、内纵横墙构成了箱形结构， 把上部荷载分配给桩。

Combined with practical engineering example of a synthetic office building for the Shanghai Minitary Police Command School,the pile box foundation was used by adding piles under the box typed foundation to fulfill the requirements for enhancing the bearing capacity and preventing the deformation.This pile box foundation is a box typed structure which consists of the bottom plate,top plate,outside wall and inside longitudinal and lateral walls,and by which the upper loadings are distributed to the piles.The paper proposes the analysis on the pile box structure,as well as its calculating methods.
