摘要
基于景洪白塔大桥静载试验的方法、内容和实际加载方案,对悬链线空腹无铰钢筋混凝土箱形拱桥的静载试验方法进行了研究,对拱桥静载试验中控制截面的挠度、应变和结构抗裂性能等测试项目的实测与计算方法进行了讨论,进而对实测值与理论值进行了比较研究并得出试验桥梁的评价结果。研究结果表明,实测值与理论值吻合,大桥的承载能力满足设计要求。
Based on the method, items and actual loading arrangement of the static loading test of the Jinghong Baita bridge the authors studied the method of static loading test on a catenary spandrel braced hingeless reinforced concrete boxed arch bridge, discussed the methods of both measuring and calculating of such testing items as deflection, strain and structural crack resistance of the sections under control in the test and then gave an assessment of the tested bridge by making a comparison between the measured values and the theoretical values. The study results show that the measured values coincide with the theoretical ones and the carrying capacity of the bridge will satisfy the design requirement.
