摘　　要：通过简化方法,建立高层建筑与地基、基础共同作用的计算模型,研究了裙房框架对大底盘框架厚筏板基础的变形、基底反力的分布的影响。计算表明,裙房不少于3层时,基础变形和基底反力的扩散范围为主楼外3跨;裙房为2层时,裙房顶层楼板的厚度应大于300mm。Based on simplified method, the interaction model among tall building, foundation and soil is set up. The deformation and reaction pressure of large-area frame structure with thick raft foundation are discussed. It can be concluded that the deformation, reaction pressure can spread to the 3 time spans outside the main building if the podium is more than 3 storeys;if the podium is 2 storeys, the thickness of the top floor plate should be more than 300mm.
