摘要
介绍了南昆铁路八渡南盘江特大桥主桥V形支撑连续梁结构的自振特性及横向刚度、舒适度斯佩林指数及狄克曼指数、抗脱轨安全度脱轨系数及卸载系数的计算结果,说明了这一新型铁路桥式结构具有良好的使用性能.
In this paper, the results of calculation of natural vibration characteristics, lateral rigidity, the Sperling and Dickeeman comfortable standards, safety factor of derailing arid off-loading coefficient about derail ing-resistance of the main spans of Badu Nanpanjiang River Bridge of Nanning-Kunming Railway are presented. And the merits of using this new type of structure of the railway bridge V-shaped supports are described.
