| 摘 要： | 下承式系杆拱桥中的系杆通常都设计为直线形,但也有因考虑道路线形要求而设计成曲线形,其对结构性能必产生影响。本文以某桥主桥为背景,采用通用有限元软件建立计算模型,通过分析不同线形的系杆对拱桥结构受力性能产生的影响,提出对竖曲线较大的系杆拱桥应在设计中考虑系杆曲线线形的影响,以得到接近实际的模拟计算结果。

| Abstract: | The tie bar in bowstring arch bridge commonly be designed for linear,but sometimes it also be designed for curve by consider road line.Based on a highway bridge,the substantial unit space finite element computation model was established,and then analyze the influence of bridge structure performance in curve tie bar,puts forward bowstring arch bridge which the vertical curve is larger than common should be considered in the influence of curve tie bar,so that close to the actual simulation results is acquired. |
