针对子材大桥成桥状态进行详细检查,利用加载车辆对大桥进行静载试验,在满足规范加载效率的前提下测量主梁及塔顶位移、主桥的各个测试截面的应力及索力,并将实测值与Midas/Civil模拟分析得到的理论值进行对比分析。研究结果表明,子材大桥受力变形正常,服役状态符合设计要求,大桥成桥状态良好。
A detailed examination was carried out on the condition of substandard bridge completion and the static load test on the bridge by using a loaded vehicle to measure the stress and cable force of the main girder and tower top displacement and each test section of the main bridge under the premise of meeting the standard loading efficiency The measured values are compared with the theoretical values obtained from the Midas / Civil simulation analysis. The results show that the deformation and normal deformation of sub-material bridge, service status in line with the design requirements, the bridge into a good state.
