【摘要】 杭州东站钢结构屋面结构为斜柱支撑。钢结构安装采用吊装和提升结合的方法,全部斜柱均采用独立临时支撑柱。其中门柱支撑落脚点进入广场地下室范围,工程采用地下地上两种复合支撑体系解决同步施工问题,并建立临时支撑和柱体结构在吊装、提升施工过程中的计算模型,对临时支撑进行了整体稳定性计算。更多还原

【Abstract】 The steel roof structure of Hangzhou East Railway Station adopted inclined column as support.The installation of steel structure adopted the combination of hoisting and lifting,and all inclined column adopted independent temporary supporting column. The gate post supporting point entered the area of basement. The project adopted over-ground and under-ground systems,which are qualified for support,to resolve problems existing in synchronous construction,and established a calculation model for the construction of hoisting and lifting temporary support and column structure,which completely calculated the stability of temporary support.更多还原
