摘　　要：对于高层建筑的桩筏基础,采用中厚板结合Mindlin-Geddes方法计算桩筏基础中筏板内力、桩基刚度及沉降。通过实例证明该方法的可行性;并针对计算沉降和实测沉降之间的差异进行分析,对计算方法提出进一步改进的建议。To calculate settlement of piled raft foundation for tall building,a thick plate-Mindlin pile method is presented,in which Mindlin-Geddes method is adopted to calculate pile settlement meanwhile raft stiffness is taken into account for differential settlement of foundation.Study of case history indicates the presented method is feasible and practical.Difference between calculated and measured settlements is analyzed and some suggestions for method improvement are given.
