| 摘 要： | 为了保证桥梁使用的可靠性,检验桥梁结构的承载能力及其工作状况,对老河口汉江铁路特大桥进行成桥静动载试验。静载试验分3种荷载工况,对每种工况均测试了关键截面的应力及挠度。动载试验对列车以不同速度过桥时墩顶及跨中截面的横向振动位移进行了量测,并测试了跨中截面的竖向动挠度。通过脉动试验,对全桥的自振频率、振型及阻尼比进行了量测。通过对实测结果和理论计算结果及规范的比较分析,表明该桥的强度、竖向及横向刚度均满足设计及规范要求,桥梁处于良好的工作状态。进行的试验及分析对同类桥型具有借鉴意义。

| Abstract: | A static and dynamic load test is carried out on the constructed Hanjiang Super-major Railway Bridge in Laohekou with to ensure the reliability of the bridge and test the carrying capacity and working condition of the bridge structure.The static load test was divided into three kinds of loading conditions,each of which tests the stress and deflection of the key sections of the bridge.The transverse vibration displacement of the piers and mid-span section was measured in the dynamic load test when the train ... |
