摘要
通过运用结构力学方法对小垂度(f/l<0.1)悬索的线形方程和初态、终态悬索内力的求解,得到小垂度悬索的线形方程和初态、终态悬索内力的一般方程.并将之运用于龙胜岩门索桥设计,该桥通行以来无任何安全问题和隐患.该方法计算简单,易于掌握,适用于山区人行索桥的设计.
With the method of structural mechanics,the general equation is developed for the first and final state force analysis for cable of small catenary suspension bridge(f/l<0.1) . Example with this method in the design of the cable of Yanmen suspension bridge in Longsheng County is shown. Practice has proved its safety and good results. Moreover, this method can be widely used in the design of walk-only suspension bridge in mountainous area. It has the advantages of simple in calculation and easy for learning, with good practical value.
