大跨度钢结构人行天桥关键节点的试验检测研究

Study on Test Detection of Key Nodes of Long-span Steel Structural Pedestrian Overpass

随着城市建设的发展,大跨度钢结构人行天桥的应用越来越多。由于环境复杂和景观要求等因素,设计、施工难度大,因此不断引入新的工艺和技术。以一座典型的大跨度钢结构人行天桥为例,说明了如何把握工程的关键节点,通过科学的试验数据和充分可靠的检测手段,保证新工艺的可行性和施工质量的可靠性,最终保证整体工程质量可靠。

With the development of urban construction, the long-span steel structural pedestrian overpass is more and more applied. Its design and construction are greatly difficult because of the complex environment and landscape requirements. Therefore, the new technologies and techniques are continuously introduced.Taking a typical long-span steel structural pedestrian overpass as an example, the article explains how to master the key nodes of the project. The scientific test data and fully reliable detection means can guarantee the feasibility of the new technologies and the reliability of construction quality finally in order to ensure the quality reliability of the whole project.
