［摘要］貴陽(yáng)街花果園N12區(qū)的某超高層結(jié)構(gòu)總高度313-4m，位于溶巖地區(qū)，核心筒下采用筏板基礎(chǔ)，柱下采用條形基礎(chǔ)。針對(duì)是否考慮施工模擬以及施工模擬中是否考慮彈簧支座等多種因素，對(duì)此超高層結(jié)構(gòu)的施工全過(guò)程進(jìn)行了仿真分析。分析結(jié)果表明：施工模擬下結(jié)構(gòu)構(gòu)件豎向位移均表現(xiàn)為先增大后減小，與傳統(tǒng)一次性加載下豎向位移的表現(xiàn)不同；同時(shí)，考慮彈簧支座會(huì)對(duì)超高層結(jié)構(gòu)豎向構(gòu)件的位移和內(nèi)力產(chǎn)生一定影響，考慮彈簧支座后該超高層結(jié)構(gòu)豎向構(gòu)件的最大位移和最大軸力都有所增加，梁端彎矩也明顯增大。因此若實(shí)際工程設(shè)計(jì)中不考慮施工模擬以及施工模擬中不考慮彈簧支座將偏于不安全。

Abstract:The super high-rise building of Huaguo Yuan N12 Project in Guiyang has a total height of 313-4m. It locates in the karst region. The raft foundation was used under the core tube and the strip foundation was used under the frame columns. The whole construction process of this super high-rise building was stimulated, concerning about whether the construction process was considered and whether the spring supports were considered in construction simulation. The results show that the vertical displacement of structural members increases first then decreases, which is different from that under the traditional one-time loading. Meanwhile, considering spring supports produces a certain influence on the vertical members of this super high-rise building with the increase of the maximum deformation and the maximum axial force. The bending moment within the end of beam increases obviously. It will be unreliable if not considering construction process or spring supports in simulation.

Keywords:whole construction process; simulation computation; spring support; foundation stiffness
