摘要: 介紹了高度約 299. 4m 的重慶俊豪 ICFC 塔樓基礎及上部結(jié)構(gòu)設計。 塔樓核心筒區(qū)域基礎為筏板基礎，外框柱區(qū)域基礎為獨立基礎，地鐵巖石破裂面影響范圍內(nèi)的裙房框架柱區(qū)域基礎為人工挖孔樁，樁基嵌入地鐵坑底巖石破裂面以下 2m，有效保證上部結(jié)構(gòu)能夠有力傳遞地鐵底的巖石破裂面以下。 塔樓采用帶環(huán)帶桁架加強層的型鋼混凝土柱￣鋼梁￣鋼筋混凝土核心筒混合結(jié)構(gòu)體系，環(huán)帶桁架增加了結(jié)構(gòu)剛度，減小層間位移角，并對環(huán)帶桁架的設置位置進行了比選分析。 動力彈塑性分析結(jié)果表明，結(jié)構(gòu)受力性能良好，能達到預期的抗震性能目標。 對塔樓進行了風洞試驗研究，選用風洞試驗荷載與規(guī)范風荷載的包絡值進行設計。 對項目與地鐵站共建、山地建筑地下室排水、酒店中庭等項目難點進行分析研究，分析結(jié)果滿足規(guī)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
