摘　　要：文章针对某大跨度独塔混合梁斜拉桥实施了静载试验,通过模拟桥梁在实际使用中的受力情况,对桥梁的变形、应力和位移等参数进行测量和分析,中跨处挠度、跨中扭转、桥墩沉降、应力测试结果均符合当前要求,桥梁的主梁和主塔均表现出良好的变形性能,桥梁结构质量良好。根据测试结果,可定期对桥梁进行检查和维护,保证桥梁结构稳定性。In this study,a long-span cable-stayed bridge with single tower and mixed beam was subjected to static load test.By simulating the actual stress of the bridge,the deformation,stress and displacement of the bridge were measured and analyzed.It was found that the deflection,mid-span torsion,pier settlement and stress test results met the current requirements,and the main girder and tower of the bridge showed good deformation performance,and the bridge structure quality was good.According to the test results,the bridge can be inspected and maintained regularly to ensure the stability of the bridge structure.
