时程分析法在大蒲春河特大桥主桥抗震验算中的应用

摘要

采用时程分析法对大蒲春河特大桥进行抗震分析,对主桥控制部位E1概率和E2概率地震作用下的响应进行验算,并利用验算结果指导该桥的抗震设计.%This paper carries out seismic analysis of Dapuchun River super major bridge by means of time history analysis method, performs checking computation for response of control part of main bridge to earthquake in E1 probability and E2 probability, and instructs the seismic design of the bridge by means of computation results.
