摘　　要：采用实用空间理论分析方法 ,解决了铁路桥中并行钢板梁桥横向加固后的力学分析问题 。By using the practicable dimensional analytic method of the highway bridge, this paper solves the mechanical analytic problem of parallel armor plating girder railway bridge which has been reinforced crossly. The result has been brought out that the crossly reinforcement of the parallel armor plating girder bridge is able to prolong the fatigue life of the bridge.
