摘　　要：对某4跨连续箱梁桥进行静、动载试验,测得试验荷载作用下桥梁结构关键力学参数的各项指标。根据实测结果与理论计算值的比较,并按相关规范,对桥梁整体性能进行评价,分析结果表明该桥各项测量指标均满足规范要求,结构处于正常弹性工作状态。这对此类桥梁结构的计算分析方法在工程中有一定的借鉴意义。Through the static and dynamic load test of a reinforced concrete continuous girder bridge, the mechanical property indexes of the bridge structure under load were measured. According to the comparison of test results with those of theoretical calculation, and in accordance with the relevant norms, the overall performances of the bridge were evaluated. The analysis re- suits show that all the indexes of the bridge could meet the requirements of the code ; the bridge was in elastic working state. The calculation of such bridge eould provide reference for similar projects.
