摘要
以湖北省科技馆新馆项目为工程背景,提出一种基于长悬臂类斜拉桥结构体系进行结构安装后的对支撑卸载的施工工艺。详细描述临时支撑拆除过程及工况,并对各过程中的支撑体系及结构力学性能状态进行分析,以确保支撑拆除全过程均安全运行,结构实体受力与变形均能满足要求。
Based on the project of the new hall of Hubei Science and Technology Museum,a construction technology of supporting unloading after structural installation of long cantilever cable-stayed bridge structure system is proposed. The process and condition of temporary support demolition are described in detail,and the supporting system and mechanical properties of the structure are analyzed in order to ensure the safe operation of the whole process of support demolition,and the stress and deformation of the structure entity can meet the requirements.
