摘　　要：在超高层建筑的施工过程中,钢结构与混凝土核心筒的同步攀升是一项关键技术,旨在有效减少施工期间的竖向变形和附加内力。研究基于南京嘉华G72项目的实际施工数据,探讨了外围钢框架或型钢混凝土、钢管混凝土框架与钢筋混凝土核心筒的框架-核心筒结构。通过等高同步攀升的建造技术,实现了结构在施工期间的优化控制,显著提高了施工效率和结构安全性。研究结果表明,该技术不仅优化了施工流程,还大幅降低了因时变因素引起的不利影响,其可为类似超高层建筑提供了可行的施工策略。In the construction process of super high-rise buildings,the synchronous climbing of steel structures and concrete core tubes is a key technology aimed at effectively reducing vertical deformation and additional internal forces during construction.this study is based on the actual construction data of the nanjing Jiahua G72 project,and explores the frame core tube structure of peripheral steel frames or steel reinforced concrete,steel tube concrete frames,and reinforced concrete core tubes.through the construction technology of synchronous climbing with equal height,the optimization control of the structure during construction has been achieved,significantly improving construction efficiency and structural safety.the research results indicate that this technology not only optimizes the construction process,but also significantly reduces the adverse effects caused by time-varying factors,providing feasible construction strategies for similar super high-rise buildings.
