There are mainly three methods in the second system stress analysis of the orthotropic steel deck, P-E method, the equivalent girderbeam method and the FEM.
This paper discusses the equivalent load of simple supported beam and continuous beam to illustrate that the loading balance method can simple the analysis and calculation of girderbeam.
通过对简支梁和连续梁等效荷载的分析，说明用荷载平衡方法可简化梁桥的分析和设计。

Combined with the engineering practice discussion is made on the construction technology and the process for the centralized prefabrication of prefabricated prestressed hollow girderbeam.
