175m预应力混凝土连续刚构桥的主梁受力分析

Main girder mechanical analysis of 175m prestressed concrete continuous rigid frame bridge

介绍了某高速公路预应力混凝土连续刚构桥的总体设计,并对主梁受力进行了有限元分析,采用两种软件分别建立全桥计算模型进行计算,结果相差不大,表明主梁受力分析是合理的。

This article introduces the overall design of a highway prestressed concrete continuous rigid frame bridge,carries on finite element analysis on main beam mechanic,uses two software to respectively establish the entire bridge calculation models and makes a calculation,and the differences of the two calculating methods are narrow,which indicates that main girder mechanical analysis is reasonable.
