摘要：随着我国交通建设的迅猛发展，桥梁作为公路和铁路连接的关键节点，更是取得了举世瞩目的成就。我国公路、铁路桥梁的建设数量均已跃居第一，出现了很多的大跨度重要桥梁，为保证重要桥梁运营状况实时可控，有必要对重要桥梁实施健康监测。桥梁实施健康监测可以及时发现桥梁病害隐患，有效预防倒塌等灾难性事故，保障桥梁运营安全。文章以灌河大桥主桥斜拉桥为依托，就斜拉桥结构健康监测系统设置进行了研究，具有较大的现实意义和工程应用前景。
Abstract: With the rapid development of China's transportation construction, bridges, as the key nodes of highway and railway connections, have made remarkable achievements. The number of highway and railway bridges in China has jumped to the first, and there are many large-span important bridges. In order to ensure that the operation status of important bridges is controllable in real time, it is necessary to implement health monitoring of important bridges. The implementation of bridge health monitoring can detect hidden dangers of bridge diseases in time, effectively prevent catastrophic accidents such as collapse, and ensure the safety of bridge operation. Based on a cable-stayed bridge, the structural health monitoring system of cable-stayed bridge is studied, which has great practical significance and engineering application prospects.
