摘要
简要介绍了我国大跨度高速铁路桥梁行车性能的研究过程与研究成果,并针对(84+160+488+488+160+84)m三塔PC箱钢桁叠合梁斜拉桥方案车桥动力性能设计研究的实例,给出了定性的结果。
In this paper, the research process and findings of train operation performance of long-span high-speed railway bridges in China are outlined, and through a design case study of train-bridge dynamic behavior of a hybrid structure of prestressed concrete box girder and steel trusses of a 3-pylon cable-stayed bridge with spans (84+160+488+488+160+84) m, the qualitative results of the train operation performance are concluded.
