摘　　要：以杭州中心项目为实例,对地铁站隧上方高21 m、悬挑28 m的大型复杂空间异形悬挑钢结构进行了施工技术的研究。施工过程采用“从下至上、分区分层、临时支撑”的方式进行吊装,同时,全程采用BIM建模技术、Midas Gen有限元分析技术、智慧监测平台实时监测技术,形成一套集高效受力分析、可视风险机制的施工流程,保障了悬挑结构和地铁车站及盾构隧道全周期安全,可为复杂工况下的钢结构工程施工提供借鉴。Using the Hangzhou Center project as a case study,construction techniques for a large-span,complex,spatially irregular cantilevered steel structure,21 meters in height with a 28-meter cantilever span above a subway station tunnel,are analyzed.The construction process adopts a bottom-up,sectional,and layered hoisting method supported by temporary structures.BIM modeling,Midas Gen finite element analysis,and a real-time smart monitoring platform are employed throughout the process,forming an efficient construction workflow that integrates structural analysis with visual risk management.This approach ensures the safety of the cantilevered structure,the subway station,and shield tunnels throughout the construction lifecycle,providing valuable references for steel structure projects under complex conditions.
