摘要
结合处于高烈度区的某(48+4×80+48)m刚构-连续梁桥的工程实例,介绍长联多跨刚构-连续梁桥按照现行铁路抗震规范进行抗震设计的全过程。分别按照多遇地震、设计地震和罕遇地震作用分析比较了常规设计、采用双曲面球型减隔震支座进行减隔震设计下该桥的地震响应,并按照抗震规范进行了抗震验算。
In this article,a(48+4×80+48)m rigid frame continuous-girder bridge in a high seismic intensity region is taken as an example,and the whole process of seismic design of the long multi-span rigid frame continuous-girder bridge based on the current railway engineering seismic standard is introduced.Further,seismic responses of the conventional seismic design and the seismic isolation design with hyperboloid spherical seismic isolation bearings are respectively analyzed and compared,and every kind of design is respectively under the low-level earthquake,design earthquake and the high-level earthquake.Moreover,seismic checking-calculations are accordingly conducted according to the current seismic design standard.
