大跨长联连续梁桥地震反应分析

某桥梁横跨黄河，是大跨度预应力混凝土连续梁桥最被广泛应用的桥型之一。对其进行抗震分析，阐述其抗震设计要点，根据桥梁的设计情况和有限元结果评价该桥的抗震性能，确保其具有良好的安全性，对超长连续梁桥的抗震分析有一定的参考价值。研究结果表明，将合理的抗震设计思想和有效的抗震措施结合起来，能取得理想的效果。

Seismic Response Analysis of Ultra Long Multi-Span Continuous Bridges

A bridge across the Yellow River is one of the most extensively applied PC continuous beam bridges. In the article the seismic response of the bridge is analyzed, the key points of the seismic design are elaborated, the seismic behavior of the bridge is evaluated according to the design of the bridge and the results of finite element analysis, in order to ensure the safety of the bridge, which has a certain refer-ence value to the seismic analysis of the ultra long continuous girder bridge. The results show that the combination of the reasonable seismic design thought and the effective earthquake resistance measures can obtain ideal effect.
