摘要
洛河特大桥是一座高墩大跨径连续刚构桥,该桥的跨度和墩高已经远远超出了我国现行公路工程抗震设计规范所规定的桥梁跨径、墩高的适用范围。因此对该桥的抗震性能分析主要采用动态时程分析方法,考虑桩-土相互作用以及地震波多点激励与行波效应,分别建立模型进行计算分析。
Luohe Bridge is a continuous rigid-framed bridge with high-piers range regulated by Specifications of Earthquake Resistant Design for Highway adopted to carry out the anti-seismic performance of beam bridge. According effect of earthquake wave, models are established separately to calculate and and long-spans. Its high-piers and long-spans are far exceed the Engineering. Therefore the dynamic time history analysis method is to pile-soil interaction, multi-support excitation and traveling-wave analyze.
