摘　　要：随着城市轨道交通快线的发展,地下区间空气动力学效应问题越来越凸显。文章探讨空气压力波影响下乘客乘车舒适度标准,分析空气动力学效应减缓措施;结合深圳地铁14号线的具体情况,对各种措施工况进行计算分析,拟定合理的区间断面,并结合区间联络通道设置泄压风管、优化运行阶段活塞风井面积等措施,减缓空气动力学效应带来的不利影响,为后期轨道交通快线的设计提供参考价值。With the development of urban rail transit express lines,the problem of aerodynamic effects in the underground sections is becoming more and more prominent.In this article,the passenger comfort standard under the influence of air pressure wave is discussed and the aerodynamic effect mitigation measures are analyzed;based on the specific situation of the Shenzhen metro line 14,calculation analysis is carried out for various measures and working conditions and reasonable sections are proposed;the measures such as pressure relief pipe,optimization of the area of the piston air ventilation shaft in the operating stage,etc.are adopted in combination with the sectional liaison passage,to reduce the adverse aerodynamic effects to provide the reference value for the design of the rail transit express line in the later stages.
