摘　　要：河南科技大学一附院肿瘤医院采用高落差整体式主裙楼筏板基础,为确保施工安全应对该基础的沉降差进行控制和分析。利用Midas GTS/NX有限元软件建立基坑荷载结构模型,分析上部结构自重及施工荷载变化对基础沉降差异的影响。结果表明:随着上部结构荷载的增加,整体式筏板基础在高落差连接处的沉降连续未发生突变;主裙楼筏板基础沉降量随着楼层荷载的增加呈非线性增加;采用整体式筏板基础能够有效控制高落差基础沉降差。The First Affiliated Hospital of Henan University of Science and Technology’s Oncology Hospital utilizes a high-difference monolithic main and podium raft foundation.To ensure construction safety,it is imperative to control and analyze the settlement differential of this foundation.The Midas GTS/NX finite element software was employed to construct a load-bearing structural model of the foundation pit,assessing the impact of the superstructure’s self-weight and the variation in construction loads on the differential settlement of the foundation.The findings demonstrate that with the increment of the superstructure’s load,the monolithic raft foundation exhibits continuous settlement at the high-difference junction without abrupt changes,the settlement of the main and podium raft foundation increases nonlinearly with the augmentation of floor loads,employing a monolithic raft foundation can effectively manage the settlement differential of the high-difference foundation.
