摘　　要：考虑高层建筑结构、基础与地基共同作用的基础上,计算研究了交错桁架体系基础固定的常规方法、条形基础、筏板基础、桩筏基础在水平荷载作用下的变形模式。计算表明,相对常规计算方法,考虑共同作用的水平变形数值有所减小,同时基础对结构下层一定范围内的刚度影响有增大趋势。On base of considering interaction function of high level architecture, base and foundation, the paper calculates and studies common fixing methods for base of staggered truss system, as well as deforming mode of strip foundation, raft foundation, pile raft foundation under horizontal loading, it shows by the calculation that comparing with the common calculating method, the horizontal deforming value is reduced when the interaction function is considered, at the same time, effects of base to rigidity in certain scope of under layer of structure is showed to he enlarged.
