摘要

西华海跨线桥采用94 m+168 m+94 m连续刚构,并建立考虑桩土共同作用的全桥有限元模型对桥梁自振特性进行分析。最后分别采用反应谱法和时程分析法对有载和无载工况下桥梁的抗震性能进行计算和对比分析。结果表明该桥的设计满足高速列车安全行驶的要求,计算方法对今后大跨度刚构桥的设计具有借鉴意义。
Xihuahai Overpass Bridge is adopting continuous rigid frame(94 m+168 m+94 m),and finite element model of the whole bridge is built on considering combined action of pile and soil.Bridge self-vibration characteristics can be analyzed by the finite element model.Then,anti-seismic performance of this bridge under loading or no-loading conditions is calculated and analyzed by means of response spectrum method and time history method separately.The results can show that this bridge design can meet the requirements of safe running of high speed train and the calculation method in this paper can provide references for similar large-span rigid frame bridge design in the future.
