为了提高桥梁建设的质量和安全性,研究采用基于静力分析和动力响应试验相结合的方法对组合桥的受力性能进行分析。在某连续梁拱组合桥的受力性能测试中发现,该组合桥在静载试验法测试下的挠度得分为89.05分;在动力响应试验法测试下的受力性能得分为86.6分,均与实际情况相似。结果表明,提出的受力性能测试方法可以准确地评估连续梁拱组合桥的受力性能。

In order to improve the quality and safety of bridge construction,a mechanical performance test method based on static analysis and dynamic response test is proposed to analyze the mechanical performance of composite bridges.In the mechanical performance test of a continuous beam arch composite bridge,it is found that the deflection score of the composite bridge under static load test is 89.05;The mechanical performance score under the dynamic response test method is 86.6,which is similar to the actual situation.The results show that the proposed mechanical performance testing method can accurately evaluate the mechanical performance of continuous beam arch composite bridge.
