摘　　要：将弹性稳定理论应用于工程实际，并全面讨论了电缆桥架的翼缘、腹板和整体稳定性问题，给出了临界载荷算式，经桥架稳定性试验考核，得出了一些实用性的结论。这不仅为电缆桥架的标准制定提供了依据，也可为其他薄壁件的稳定设计计算作参考。The stability of the flange plate,web plate and the integral structure of the cable bridge is discussed adequately,using stability theory of elastic structure.A formula for critical load of the bridge has been derived through choosing an appropriate stress function,and the calculation corresponds with the test results of the bridge stability.This paper documents conclusions which are useful in laying down design standard of the cable bridge and stability design of other thin walled structure.
