高架车站设计涉及城市轨道、铁路、房屋建筑等不同行业设计规范,为达到安全运营的目标并符合各专业方向的抗震规范要求,进行抗震专项设计是其中的重要环节.按三水准地震等级进行三阶段设计是目前的主要设计思路,同时采用静力弹塑性方法进行补充分析,可进一步了解结构的薄弱环节并进行补强措施.以某高架车站设计为例,列出了各阶段主要设计目标、设计结果、考核指标,对高架车站结构的抗震性能进行综合评价和设计研究.结果表明高架车站满足三水准下的抗震要求,在静力弹塑性分析下,车站结构的站台层发生轻微损伤.所得结果可供类似高架车站提供参考.
SPECIAL SEISMIC DESIGN AND ANALYSIS FOR A CITY RAILWAY ELEVATED STATION
The design of elevated stations involves codes of urban railways,railroads,and housing buildings.The special seismic design is an important part to achieve the goal of safe operation and to meet the seismic code require-ments of each professional direction.According to three-level seismic grade,the three-stage design for stations is the main idea at present.Static elastic-plastic method is used to carry out supplementary analysis,by which the structural weaknesses are exposed,and the reinforcing measures are proposed.Taking the design of an elevated sta-tion as the case,the main design objectives,design results,and assessment indexes of each stage are presented,and the seismic performance of the elevated station structure is comprehensively evaluated.The results indicate that the elevated station meets the three-level seismic grade,and the platform layer of the station structure undergoes slight damage under static elastic-plastic analysis.The obtained results may provide the reference for similar elevated sta-tions.
