The article tests the dynamic and static load of a 30-year double-curved arch bridge.The static test shows that： hollow top wet arch connector has great impact upon structural bearing capacity and horizontal load distribution.However,the dynamic test shows that： the dynamic characteristics test result will be treated as basis of evaluating the bridge conditions.%对某座使用30年的双曲拱桥进行静动力荷载试验,通过静力试验表明,拱顶湿接头的空洞对结构的承载能力和荷载横向分布有较大的影响,而动力试验表明,本桥的动力特性测试结果可以作为评判本桥状况的依据。
