摘　　要：斜拉桥作为一种拉索体系,比梁式桥有更大的跨越能力,由于其良好的力学性能和经济指标,已成为大跨度桥梁 中最主要的桥型。它的受力特性及多跨斜拉桥易产生的特殊问题——拉索振动,亦可以采取不同类型的防范措施来加以控制。The starting drag crossing bridge is a system, it has a stronger capability in crossing than the bridges with beams. It is a main type in the big bridge with it's best mechanics character and economical index. But it easily brings troubles with it's character in strength and crossing with slanting-drag. How to settle down the vibration of drag-link.
