摘要
沪通长江大桥是世界首座主跨超过1 km的公铁两用斜拉桥,其建造和运维面临众多技术挑战,需开展多项科研攻关。保证科研立项精准、科研成果可靠实用是大桥科技管理工作的核心目标。本文首先介绍了沪通长江大桥概况和技术难点,其次对专题科研内容、管理措施和取得成效进行了总结,并介绍了为解决现场施工难题开展的进一步研究工作。从科研管理角度,提出"调研-研究(试验)-专家评审"的管理思路和"阶段总结-专家评审-优化调整"的过程管理方法。为及时固化大桥建设成果,提出工程、技术总结与大桥建设同步的理念。最后对大桥科研及管理、施工工艺等给出了一些总结性建议。
Shanghai-Nantong Yangtze River Bridge will be the world＇s first highway and railway cable-stayed bridge with its main span more than one kilometer after being built.Technical breakthrough in its construction and maintenance needs the support of scientific research.The aim of management of science and technology is to guarantee the reasonability and practicability of research projects.In this paper,brief introduction and technical challenges were first presented.Then summary was given on specialized research,project management and its effects.And further research on construction challenges was also introduced.Management idea and process management method were proposed.The former actually showed a proper management procedure composed of investigation,research（test） and expert review.And the latter consisted of three steps including stage summary,expert review during the research,and optimization and adjustment.Experience from design and construction of the bridge was also required to summarize in the same pace with construction,including management and technical summarization.Suggestion was also put forward in terms of research,managementand construction.
