［摘要］南京青奧中心雙塔地下均為3層，地上分別為58層（高255m）和68層（高314.5m），采用了矩形鋼管混凝土“密柱”框架-鋼筋混凝土核心筒結構，取消了加強層，并采取地下結構全逆作法施工，是目前世界上最高的超高層建筑全逆做法施工案例之一。通過與建筑師的密切配合以及對項目的深入理解，結構設計師提出了符合多重目標的結構方案，保證了工期目標的實現(xiàn)。從建筑方案的演化過程、結構選型、抗震分析、基礎設計、施工逆作設計以及施工模擬分析等多個方面介紹了該項目的設計特點、技術難點以及相應的解決措施，獲得了良好的綜合技術經(jīng)濟效益。［關鍵詞］南京青奧中心; 逆作法施工; 密柱框架-核心筒; 高強混凝土擴頂灌注樁; 一柱一樁; 施工模擬中圖分類號：TU355，TU973 文獻標識碼：A 文章編號：1002-848X(2016)11-0001-08
Summarization of research on the structural design of the super high-rise twin towers of Nanking Youth Olympic CenterLiu Wenting1, Ren Qingying1, Zhao Qingyu1, Yang Songlin1, Li Sen1, Zhang Xiaoyu1, Zhang Liangping2, Dong Hexun2, Mao Weibing2, Zhao Subei2(1 China Architecture Design Institute Co., Ltd., Beijing 100044, China; 2 Nanjing Branch of Huasen Architectural & Engineering Designing Consultants Co., Ltd., Nanjing 210005, China)Abstract: The super high-rise twin towers of Nanking Youth Olympic Center has 3-layer basements underground for both towers and 58 layers (255m) and 68 layers (314.5m) for each tower respectively. It adopts rectangular concrete filled steel tube concrete dense columns frame-reinforced concrete corewall structural system without strengthening layers. The top-down construction method is applied in all underground structures, and the structure is one of the tallest buildings constructed by the top-down technique. By working together with the architects and through deep researching on the project, the structural engineers proposed the multi-object structural design scheme to ensure the realization of construction time. The evolution of the architectural plan, the structural system selection, the seismic analysis, the foundation design, the top-down method design and the construction simulation analysis were presented. The design details, technique difficulties and corresponding measures were introduced. The high comprehensive technical economic efficiency was fully achieved in this project.Keywords: Nanking Youth Olympic Center; top-down construction method; frame-tube structural system with dense columns; cup-shaped bored pile with high strength concrete; one pile under one column; construction simulation
