Study on the Causes and Countermeasures of Bridge Collapse in China

Under complex operating environment and natural disasters, bridges may face the risk of collapse. Aiming at bridges in China, this paper explores the causes of bridge collapse and the corresponding countermeasures. In this paper, firstly, the basic situation of bridge collapse in China in recent years and the serious losses caused by it are analyzed. Then, taking the Wenchuan earthquake and the flood in 2010 as examples, the paper analyzes the bridge collapse accidents caused by natural disasters and the serious impact on the health of bridges. Finally, in view of earthquake and flood, the countermeasures and solutions to prevent bridge collapse are put forward. The results show that the safety of bridge structure is very important, and its ability to resist human factors and natural disasters should be considered during the whole life cycle including design, construction and operation periods. This paper can provide some theoretical reference for bridge collapse resistance research.
