柔性悬索桥维修方案的优化

Scheme optimization for a flexible suspension bridge's maintenance

针对某盐卤管道吊桥由于使用期间跨中不断下挠,无法保证安全运营的情况,从结构主要受力构件的强度入手,论证了直接在原有主缆上进行维修的可行性,采取调整主缆线形,减缓主梁局部弯曲的方法,圆满解决了这一问题,并用有限元软件ANSYS对优化方案进行了分析计算。

A suspension bridge for bittern transport. Because of during operating period in drop continuously can＇ t guarantee safe operation, this paper starts with the receives force from component mainly of the structural strength the receives force component mainly, has expounded and proved the feasibility that repaired directly on original main push-towing rope, adopts the method of adjustment line shape of main push-towing rope, slowsdown the curved of main beam part, is satisfactory to have solved this problem, and the finite dement software ANSYS is used to analysis.
