摘要
采用SAP2000程序，对铁路淮河特大桥进行了反应谱分析和时程分析，分析表明地震力不控制主梁结构设计，但地震力直接作用于墩底，须对连续梁的墩底进行抗震应力验算，连续梁桥的支座承担较大剪力，建议采用抗震支座，以策安全。
This paper taken response-spectrum analysis and time-history analysis to the Huaihe grand bridge by SAP2000 program. The result indicated that seismic force didn＇ t control main beam design, but it acted directly on the bottom of pier. So seismic force acting on the bottom of pier of continuous beam must be verified. The paper suggested that seismic bearing should to be adopted for safety since the bearing of continuous beam taken much shearing force.
