摘要: 介绍了高度约 299. 4m 的重庆俊豪 ICFC 塔楼基础及上部结构设计。 塔楼核心筒区域基础为筏板基础，外框柱区域基础为独立基础，地铁岩石破裂面影响范围内的裙房框架柱区域基础为人工挖孔桩，桩基嵌入地铁坑底岩石破裂面以下 2m，有效保证上部结构能够有力传递地铁底的岩石破裂面以下。 塔楼采用带环带桁架加强层的型钢混凝土柱￣钢梁￣钢筋混凝土核心筒混合结构体系，环带桁架增加了结构刚度，减小层间位移角，并对环带桁架的设置位置进行了比选分析。 动力弹塑性分析结果表明，结构受力性能良好，能达到预期的抗震性能目标。 对塔楼进行了风洞试验研究，选用风洞试验荷载与规范风荷载的包络值进行设计。 对项目与地铁站共建、山地建筑地下室排水、酒店中庭等项目难点进行分析研究，分析结果满足规范要求。

Abstract:The foundation and upper structure design of Chongqing Junhao ICFC tower with a height of about 299. 4m wereintroduced. The foundation of the core tube region of the tower was a raft foundation， and the foundation of the outer framecolumn region was a single foundation. The foundation of the podium frame column region within the influence of the subwayrock fracture surface was a manual digging pile， and the pile foundation was embedded 2m below the rock fracture surfaceof the subway pit. It can effectively ensure that the upper structure can effectively transmit the rock below the fracturesurface of the subway bottom. The tower adopts a steel concrete column￣steel beam￣reinforced concrete core tube mixedstructure system with a ring￣belt truss reinforcement layer. The ring￣belt truss increases the structural rigidity and reducesinterlayer displacement angle. The setting positions of the ring￣belt truss were compared. The dynamic elastoplastic analysisresults show that the structure has good mechanical performance and can achieve the expected seismic performance target. Awind tunnel test study was conducted on the tower， and the envelope value of the wind tunnel test load and the normativewind load was selected for design. The project difficulties of subway station co￣construction， mountain building basementdrainage， hotel atrium were analyzed and studied， and the analysis results meet the requirements of the specification.

Keywords:high￣rise structure； subway co￣construction； mountainous building； steel reinforced concrete； ring￣belt truss；dynamic elastoplastic time history analysis
