Abstract：By comparing the numerical calculation results of two models,single high-rise building and its high-rise buildings system,the effect on super structure-foundation-soil interaction of adjacent high-rise buildings simultaneous construction is analyzed based on a large number of the measured data of field research using FLAC-3D,including the deformation and mechanical characteristics of pile-raft foundation and soil.The results show that when considering the interaction,adjacent high-rise buildings constructed simultaneously will cause the additional stress superposition and spreading around;the maximum settlement areas occurs an offset and the differential settlementis increased;the raft compressive stress is decreased,while the tensile stress is increased;the pile axial force is increased obviously,especially the pile-top axial force.The effect of adjacent high-rise buildings simultaneous construction in medium-term construction is more obvious.
