在中环5.23事故抢修工程中,上海市建筑科学研究院承担了结构检测与监测、顶升过程监控、复位通车后运营监测评价等一系列工作,作为技术服务单位对抢修全过程提供了良好的技术支撑和保障。在分阶段对所做工作进行技术总结的基础上,提出了重视对桥面宽度与支座间距比偏大的结构形式管养的建议。

In the steel beam rolling repair engineering on the 23 rd of May for Shanghai Central Viaduct, Shanghai Research Institute of Building Sciences Group undertook a series of work such as structure detection and monitoring, jacking process monitoring, operation monitoring and evaluation after opening, and provided well technical support in the whole process of repair work as the technical service provider. Based on these technical work,more attention suggestions are put forward to to the maintenance of structure with large ratio of deck width to bearing spacing.
