随着我国社会经济和交通运输事业的快速发展,过去年代修建于各地城镇和各级公路上的桥梁,负担着十分沉重的交通荷载及繁重的交通量。近20年来桥梁抗风、抗震领域的研究成果以及新材料新工艺的开发推动了大距度桥梁的发展;同时,随着人们对大型重要桥梁安全性、耐久性与正常使用功能的日渐关注,桥梁健康监测的研究与监测系统的开发应运而生。 With the rapid development of social economy and transportation in our country, bridges built in cities and towns and roads at various levels in the past have burdened a heavy traffic load and a heavy traffic volume. In the recent 20 years, the bridge wind resistance, the research results in the field of aseismic and the development of new materials and new technologies have promoted the development of large-span bridges. At the same time, as people pay more and more attention to the safety, durability and normal function of large important bridges, The development of bridge health monitoring research and monitoring system came into being.
