摘要
针对大多数设计人员在城市轨道交通隧道设计过程中对空气动力学效应指标考虑不全面、相关规范对中低速磁浮双线隧道压力舒适度标准及净空面积的规定存疑的现状,文章结合以往工程经验提出了考虑空气动力学效应的城市轨道交通隧道设计方法,通过对比分析不同城市轨道交通系统规范明确了中低速磁浮双线隧道压力舒适度标准,相关成果在湖南凤凰磁浮双线隧道设计中得到良好应用。
During design of urban rail transit tunnels,most designers cannot comprehensively consider the aerodynamic effect indexes.Besides,the passenger ear comfort standards and the corresponding clearance area standards for the medium and low speed maglev double line tunnel are in doubt in the relevant codes.To address these issues,the urban rail transit tunnel design methodology is proposed in consideration of aerodynamic effects and based on the previous experience.Through the comparative analysis of different urban rail transit codes,the passenger ear comfort standard for the medium and low speed maglev double line tunnel is clearly stated,and the related research achievements are successfully applied to the design of Hunan Fenghuang maglev double line tunnels.
