摘　　要：合肥CBD中央广场工程为一大底盘多塔楼建筑 ,若按常规方法施工 ,则必须按《混凝土结构设计规范》要求预留伸缩缝。但伸缩缝的留设会影响建筑物的使用功能。根据计算分析结果 ,在采取多项技术措施的前提下 ,取消了伸缩缝 。The central plaza in Hefei CBD have 5 towers on the podium. The longitudinal and cross length of the podium is about 119 5m and 81 1m respectively. With the common construction method, the expansion joint should be preformed according to the concrete design code. The existance of the expansion joint cannot satisfy operating requirement.Several technical measures, in response to the results of the analysis, are introduced to eliminate the expansion joint and the discrepancy between the usage and design code.
