摘要
本课题组对万县长江大桥主跨４２０ｍ用钢筋混凝土拱的施工过程进行了模型试验，模型为十分之一比例尺，实例各施工阶段的挠度和应力，并与理论值进行了比较。最后从破坏试验显示该模型具有足够的安全储备。
Amodel RC arch with steel tube frame to simulate the construction procedure of Wanxian Yangtze River bridge whose main span is 420 m has been tested. The model scale is 1/10. In this peper,the stress and deformations measured in the arch construction steps of the model are compared with the theoretical values.Finally the ultimate strength test whows that there is Plenty safty margin for model arch.
