摘　　要：石长线湘江铁路正桥是我国最大跨度的预应力混凝土连续梁桥,该桥1998年建成以来,已经过10年的运营。为了对大跨度的预应力混凝土连续梁铁路桥进行动力学性能试验评估,目前已全面了解该桥的工作状况。为了取得较好的试验结果,文章对试验方案进行了较详细的研究。Xiangjiang river main bridge in Shichang railway is the longest precast continous beam bridge. After it＇s being constructed in 1998, it has been performed for more 10 years. In order to carry out the dynamic performance test evaluation on the long-span continuous prestressed concrete beam bridge, we have fully known the working situation of this bridge. In order to achieve better results, the article carried out a more detailed study on the pilot program.
