［摘要］以陕西省延长石油科研中心大厦超高层项目为对象，运用MIDAS/Gen软件，考虑结构刚度、几何形态、边界条件、施工荷载以及材料性质的时变特性，对结构进行施工过程仿真模拟，对传统加载模拟、未考虑找平施工模拟和考虑找平施工模拟三种计算方案下的结构竖向变形进行对比分析，并对外框柱、核心筒的竖向变形组成成分以及不同施工找平措施下二者竖向变形差进行对比分析。结果表明：考虑找平的施工模拟计算结果与传统加载模拟和未考虑找平的施工模拟计算结果差异较大，得到的结构施工竖向变形规律表现为中间大、两端小；弹性变形对结构竖向总变形起控制作用，徐变变形次之，收缩变形影响最小；混凝土收缩、徐变以及施工找平因素对结构竖向变形规律影响较大，不容忽视。

Abstract:The construction process simulation was conducted on the super high-rise building named Yanchang Petroleum Scientific Research Center located in Shaanxi Province by using the  MIDAS/Gen software, considering the time-varying characteristics including the structural stiffness, geometric shape, boundary conditions, construction loads and material properties. Comparison analysis was conducted on the three calculation schemes of structural vertical deformation, including traditional loading simulation, construction simulation without considering leveling, and construction simulation considering leveling. The vertical deformation components of frame columns and the core tube, and the structural vertical deformation differences between them under different construction leveling measures were analyzed in comparison. The results show that the calculation results of construction simulation considering leveling are quite different from results of traditional loading simulation and construction simulation without considering construction leveling. The structural vertical deformation law of structure construction features large in the middle and small at the both ends. The electric deformation takes controlling role in the overall structural vertical deformation, while creep deformation follows and shrinkage deformation has least effect. Factors like concrete shrinkage, concrete creep and construction leveling have great effects on the law of structural vertical deformation and cannot be ignored.
