针对重庆轻轨2号线二期工程和3号线,特进行新型跨度为25 m直线PC轨道梁1∶1模型静力抗弯试验研究。给出了该试验梁的荷载布置、荷载设计和静载试验结果,如挠度试验结果、应力试验结果和结构校验系数,得出了25 m直线PC轨道梁静载试验结论。试验结果表明,该新型PC轨道梁可以应用到实际工程中去。
For Chongqing Light Rail Line 2 Phase II and Line 3, a new type of span 25 m linear PC track beam 1: 1 model static bending test. The load distribution, load design and static load test results of the test beam, such as deflection test results, stress test results and structural calibration coefficients are given. The static load test results of 25 m linear PC track beam are obtained. The test results show that the new PC rail beam can be applied to the actual project.
