摘要
渝怀线长寿长江大桥为双线下承式连续钢桁梁,介绍桥梁静动力试验成果,结合有限元理论分析,将试验结果与计算结果及规范值进行比较,评价桥梁现状。
Changshou Changjiang River Bridge on Chongqing-Huaihua Railway is a doubletrack continuous through steel truss girder bridge. In this paper, the results of the static and dynamic load tests made for the Bridge are presented. Based on the finite element analysis, the resuits of the tests are then compared to those of the calculations and to the values in the codes and specifications, and the current conditions of the Bridge are evaluated.
