| 摘 要： | 目前，随着交通量的加大，国内存在的大量旧桥均需做相应的验算或者加固，以便确保旧桥的实际承载能力能满足荷载要求。本文利用有限元程序,以国内某座连续索桁混合结构的旧桥为例进行验算，得到在大桥在原来和现有交通荷载等级的条件下的承载能力，为国内相应的旧桥验算提供经验。

| Abstract: | With the increasing traffic volume,most of bridge must make corresponding calculation or reinforcement in order to assure the practical bearing capacity can satisfy the requirement.In order to provide experience for checking,a domestic cable truss bridge of mixed structure for an example is made of,and calculated the load bearing capacity of the bridge by using finite element program. |

| Keywords: | finite element Cable truss mixed structure load combinations |
