Discussion on Soil Reaction Spread of Whole Foundation for Tall Building with Podium

摘要: 用理论模型和有限元方法,对天然地基上高层建筑主楼和裙房连体筏板地基反力分布作进一步研究:得出地基反力从高楼向裙房扩散的范围和数量主要取决与筏板厚度,地基土变形模量及高层主楼荷重;在本模型计算中为2~4跨。经与实际工程对比,找出理论模型与实际工程差别的原因;并指出筏板厚度在抵抗地基土反力扩散中起主要的作用。Abstract: Through finite element analisys method, the model of soil reaction spread is set up. It is obtained that the soil reaction spread principally is dependent on raft thick, elastic modulus of soil and loads of tall building. In fact the reaction spread is reduced from concret wall of tall building to frame of podium,and the spread range about is 2~4 spans of podium.
