结合工程实例，以某水库中的连续刚构桥为工程背景，研究水深对桥梁地震效应的影响。计算了桥梁在无水状态下地震的动力响应，模拟有水状态下桥墩与流体的耦合作用，建立了不同水深状态下的有限元模型，计算了不同水深时地震的动力响应并做了对比分析。结果表明，随着水深的增加，水对桥梁结构的内力产生了重大影响，桥梁在地震作用下的应力有增加的趋势，且纵桥向地震波作用下，地震响应比横桥向地震波作用下响应要剧烈。
結閤工程實例，以某水庫中的連續剛構橋為工程揹景，研究水深對橋樑地震效應的影響。計算瞭橋樑在無水狀態下地震的動力響應，模擬有水狀態下橋墩與流體的耦閤作用，建立瞭不同水深狀態下的有限元模型，計算瞭不同水深時地震的動力響應併做瞭對比分析。結果錶明，隨著水深的增加，水對橋樑結構的內力產生瞭重大影響，橋樑在地震作用下的應力有增加的趨勢，且縱橋嚮地震波作用下，地震響應比橫橋嚮地震波作用下響應要劇烈。

A continuous rigid frame bridge was taking as engineering background to study the impact of water depth on seismic response of bridge ,the dynamic response of the bridge in anhydrous condition was calculated .The fluid‐solid interaction between piers and water was simulated and finite element models under different water depth condition were established ,the dynamic response analysis was car‐ried out in order to compare with anhydrous condition .The results showed that with the increase of water depth ,it had a significant impact on the stress of bridge structure .As the water depth in‐creased ,the stress of the structure was increased ,and the seismic response was violent when the ori‐entation of seismic waves was along the bridge .
