| 摘 要： | 下承式拱桥考虑吊杆非保向效应的面外稳定性研究,以桥道梁横向为有限刚度,并考虑拱自重不参予吊杆力,以及拱肋不同的矢跨比等条件,计算出非保向影响对临界力的效应系数.有关成果可供设计下承式、中承式拱(包括系杆拱)的总体布置参考.

| Abstract: | The out-of-plane stability of through arch bridge considering the non-directional effect of suspender was studied with limited lateral stiffness of bridge and the consideration that the arch weight did not participate in the suspender force.The effect coefficient of non-directional influence on critical force was calculated under different rise-span ratios of arch ribs.The results could be used as a reference for the overall layout of the lower and middle arches,including tied arches. |
