摘要：

以长三角生态绿色一体化发展示范区嘉善展示馆预应力木结构施工为研究对象,探讨预应力大跨胶合木结构关键施工技术和施工模拟分析。 通过 Revit 软件对钢木结构施工过程进行模拟推演,实现施工可视化,使木构件在电脑端预先精确拼装。 通过 MIDAS Gen 软件仿真模拟,比较 2 种不同施工方案,重点分析施工过程中杆件位移和内力变化。 结果表明,先架设梁、柱再张拉预应力索的方案,在控制内力和变形方面表现更优,有效提高了施工效率,并确保了结构整体稳定与安全。 此外,模拟结果与现场监测数据的对比分析进一步验证了模拟结果的准确性,为施工方案的优化提供了科学依据。

Taking the prestressed wood structure construction of Jiashan Exhibition Hall in the YangtzeRiver Delta ecological green integration development demonstration area as the research object, the keyconstruction technology and construction simulation analysis of prestressed large-span glued laminatedwood structure are discussed. Through Revit software, the construction process of steel-wood structure issimulated and deduced, and the construction visualization is completed, so that the wood components canbe assembled accurately in advance at the computer end. Through the simulation of MIDAS Gensoftware, two different construction schemes are compared, and the displacement and internal forcechanges of the components during the construction process are analyzed. The results show that the schemeof erecting beam-column first and then tensioning prestressed cable has better performance in controllinginternal force and deformation, which effectively improves the construction efficiency and ensures theoverall stability and safety of the structure. In addition, the comparison between the simulation resultsand the field monitoring data further verifies the accuracy of the simulation results and provides ascientific basis for the optimization of the construction scheme.
