比较了《建筑抗震设计规范》、《城市轨道交通结构抗震设计规范》和《铁路工程抗震设计规范》在高架车站设计中所用地震参数的异同,包括地震重现期、反应谱曲线构成、衰减指数等,得到《城市轨道交通结构抗震设计规范》对多遇地震下低烈度区软弱场地的地震作用提高最多,比《铁路工程抗震设计规范》约提高30%,比《建筑抗震设计规范》约提高80%。通过某场地条件下高架车站墩柱截面设计比较,得到《城市轨道交通结构抗震设计规范》比《建筑抗震设计规范》圬工量提高20%。
The similarities and differences of the seismic parameters used in the design of viaduct stations are compared, such as the seismic recurrence period, the composition of the reaction spectrum curve, the attenuation index And so on, the “seismic design code of urban rail transit structure” is the most improved in the weak area under the earthquake with low seismic intensity, which is about 30% more than the “Code for Seismic Design of Railway Engineering” and about 30% higher than the “code for seismic design of buildings” 80%. Through the design comparison of pier column section of elevated station under a certain site conditions, the “seismic design code of urban rail transit structure” is increased by 20% over that of “code for seismic design of buildings”.
