［摘要］以陜西省延長(zhǎng)石油科研中心大廈超限高層項(xiàng)目為工程背景，基于施工階段疊加法的分析原理，同時(shí)考慮混凝土材料收縮徐變特性、混凝土核心筒配筋率的影響以及伸臂桁架延遲連接措施，運(yùn)用MIDAS/Gen軟件對(duì)該項(xiàng)目進(jìn)行施工過(guò)程模擬，計(jì)算分析塔樓竣工時(shí)刻結(jié)構(gòu)的豎向變形和次結(jié)構(gòu)（如伸臂桁架）的附加應(yīng)力，并通過(guò)簡(jiǎn)單的理論公式推導(dǎo)得出結(jié)構(gòu)豎向構(gòu)件預(yù)找平計(jì)算方法，在此基礎(chǔ)上，求出結(jié)構(gòu)豎向構(gòu)件預(yù)找平值，為施工方確定構(gòu)件下料長(zhǎng)度提供參考，彌補(bǔ)構(gòu)件變形，盡可能使結(jié)構(gòu)在竣工后滿足設(shè)計(jì)要求。

Abstract:Based on  the super high-rise building of Yanchang Petroleum Scientific Research Center located in Shaanxi Province, software MIDAS/Gen was used to conduct the construction process simulation on the project based on the construction stage superposition method, considering  shrinkage and creep of concrete, reinforcement ratio of the concrete corewall and measures that delaying connection of outriggers. The vertical deformation of the tower at the moment of completion and the additional stress of the secondary structure (such as the outriggers) were calculated and analyzed. Simple theoretical formula was used to derive pre-leveling calculation method of vertical components. On this basis, pre-leveling value of the vertical structural component was calculated, which provide references for the construction party to determine the component blanking length to make up for the deformation of the component and to make the structure meet the design requirements after completion as far as possible.

Keywords:construction stage superposition method; shrinkage and creep; additional stress; delay connection; pre-leveling
