摘要: 为了检验常熟碧溪大桥施工质量是否符合设计要求,保证桥梁使用的安全性,根据设计荷载和有关规范进行了结构分析,制定了静载试验方案,并对试验数据进行了分析。试验结果显示:大桥实际承载力及变形状态与理论计算基本吻合,结构的强度和刚度满足设计要求,卸载后回零良好,结构工作时处于弹性状态,桥梁工作性能满足设计和安全运营要求。
Abstract: In order to test whether the construction quality of Bixi Bridge in Changshu meets the design re-quirements, and to ensure the safety of the bridge, the structure was analyzed and a static load test program was developed according to the design loads and the relevant specifications. Then the test data were analyzed. Test results showed that: the actual capacity and deformation of the bridge are consistent with the theoretical results. The strength and stiffness of the structure meet the design requirements. The stress moves back to zero well after unloading and the structure works are in an elastic state. The performance of the bridge meets the requirements of design and security operations.
