摘要
成都双流国际机场T2航站楼钢结构为箱形桁架主拱与双层网架的组合结构,由16榀主拱单元组成,具有跨度大、质量大的特点。由于现场路桥工程、混凝土工程和钢结构工程交叉施工,施工场地有限,因此钢结构安装方案采用滑移施工技术。运用有限元软件对混凝土结构、滑移支撑结构、钢结构进行施工过程仿真模拟分析,确保滑移施工安全可靠,结果表明该滑移施工方案是合理可行的。
The steel structure of Chengdu Shuangliu International Airport T2 terminal includes 16 boxsection truss main arch and double grid. It has some structural characteristics such as larger span andgreat weight. The sliding construction technology of erection scheme is used because of the crossconstruction in road-bridge structure, concrete structure and steel structure. The construction process ofconcrete structure, sliding support structure and steel structure are simulated and analyzed by FEMsoftware to meet the security and reliability. The results show that the sliding construction scheme isfeasible.
