摘要
对于需要用动静载试验来检查健康状况的多跨桥梁,大多要选择几个试验桥跨进行试验,试验跨选择的正确与否,直接关系着试验结果的正确性。通过工程实例,推荐一种对多跨桥梁选择试验桥跨的方法。
For health inspection of a multiple-span bridge in need of dynamic and static load tests, on most occasions, several tested spans will be first selected form the bridge for the purpose of the tests. The right or wrong selection of the tested spans normally has a direct bearing on the correctness of the test results. With reference to an engineering example, a method suitable for selecting the tested spans from multiple-span bridges is recommended.
