摘要: 蘇州中南中心是采用巨型框架?核心筒?伸臂桁架結(jié)構(gòu)體系的超高層建筑,原方案(建筑高度 729m,地下 5層)的樁基和地下連續(xù)墻已施工完畢,現(xiàn)調(diào)整為建筑高度 499. 15m、地下 6 層的方案. 該工程具有周邊環(huán)境復(fù)雜、順逆結(jié)合施工、需充分利用原有已施工樁基和地下連續(xù)墻等特點. 首先介紹了該工程地下室設(shè)計難點及其處理方法. 其次,對層數(shù)較多、深度較大的地下室樓板進(jìn)行了穩(wěn)定分析. 此外,結(jié)合超高層建筑地下室頂板受力復(fù)雜的特點,進(jìn)行了塔樓水平力作用下地下室頂板應(yīng)力分析. 計算結(jié)果表明,結(jié)構(gòu)滿足規(guī)范要求.

Abstract:Suzhou Zhongnan Center is a super high?rise building which adopts huge frame?core tube?outrigger truss system.Pile foundations and underground diaphragm walls of original scheme which was 729m building height and 5 floors ofbasement have been completed, but now it is modified to 499. 15m building height and 6 floors of basement. The project hasthe characteristics of complex surrounding environment, combination of down?top and top?down construction, andrequirement to make full use of original constructed pile foundations and underground diaphragm walls. Firstly, the designdifficulties of the basement of the project and its treatment methods were introduced. Secondly, the stability analysis of thebasement floor with more floors and great depth was carried out. In addition, combined with the complex stress of basement roof of super high?rise building, the stress analysis of basement roof under the action of tower horizontal force wasconducted. Computational results show that the structure meets the specification requirements.
Keywords: super high?rise building; huge frame?core tube?outrigger truss; combination of down?top and top?downconstruction; stability analysis; stress analysis of top roof of the basement
