本文通过室内大型模拟试验 ,对双塔楼非并列布置于同一大底盘框架厚筏结构与地基共同作用问题进行了研究 ,得出了筏基变形和基底反力分布特征 ,提出任意组合的多组塔楼共同作用于同一大底盘框架厚筏基础上的结构体系 ,其地基基础的变形特征为 :各塔楼独立作用下产生的变形效应通过以各个塔楼下面一定范围内的区域为沉降中心 ,各自沿径向向外围衰减 ,并在其共同的影响范围内相互叠加而形成 ;基底反力的分布规律为 :各主塔楼荷载以其塔楼下某一区域为中心 ,通过各自塔楼周围的裙房基础沿径向向外围扩散 ,并在其共同的荷载扩散范围内 ,基底反力相互叠加。
In this paper, a large-scale indoor simulation experiment is conducted to study the interaction between thick raft structure and foundation which are not arranged in parallel on the same chassis frame of twin towers. The characteristics of raft deformation and the reaction force of substrate are obtained. Under the common structural framework of the same large chassis frame with thick raft, the deformation characteristics of foundation foundation are as follows: the deformation effect caused by the independent action of each tower is obtained by taking the area within a certain range under each tower as the settlement center, To the periphery decay, and their mutual influence within the scope of the formation of superimposed; substrate reaction force distribution law: the main tower load in its tower under a certain area as the center, through the podium around the skirt foundation along the radial Diffuse to the periphery, and in the range of their common load diffusion, the reaction force of the substrates is superposed on each other.
