摘要
随着我国交通运输事业的快速发展,桥梁特别是跨铁路桥梁的健康运营越来越受到关注。而桥梁技术状况评定是评估桥梁健康状况的重要方法.以湖南省某跨铁路桥梁为例,通过桥梁技术状况评定、无损检测、结构验算及动静载试验等方法检测桥梁的安全状况。结果表明,桥梁总体技术状况总体为4类,桥梁承载力及整体刚度满足相关规范要求。为保障该桥梁健康运营,建议对桥梁进行限载、限重。
With the rapid development of Chinese transportation,the healthy operation of Bridges,especially across railway Bridges,has attracted more and more attention.The assessment of bridge technical condition is an important method to evaluate bridge health.Taking a cross-railway bridge in Hunan Province as an example,the safety condition of the bridge was tested by means of technical condition assessment,non-destructive testing,structural checking calculation and dynamic and static load test.The results show that the overall technical status of the bridge is divided into four categories,and the bearing capacity and overall stiffness of the bridge meet the relevant specifications.In order to ensure the healthy operation of the bridge,it is suggested to limit the load and weight of the bridge.
