摘　　要：列车高速过站引发的气动效应问题,是新广州火车站风工程研究的专题之一。本文基于先进的CFD数值模拟仿真平台,采用"动网格"技术对列车高速过站进行数值模拟研究,一方面对压力波的传递对屋盖结构压力分布的影响进行定量评估,为结构设计提供参考和建议;另一方面,给出高速列车通过时站台区域风速的空间分布范围,结合风环境舒适性评估标准(其中包含危险性风速范围),从而给出站台区域人员活动的安全和舒适范围。The strong aerodynamics phenomenon caused by the high-speed train is numerically researched in this paper by using the dynamic mesh method,which is one of a series of wind engineering researches for the New Guangzhou Railway Station.The effect of the pressure wave generated by the high-speed train on the roof structures is analyzed firstly in order to provide referential suggestion for the structural design;then the effect of the wind environment in the range of platform is analyzed.The spatial distributions of wind velocity are illustrated,and the ranges for the pedestrian safety and comfort are given based on the proper wind force criterion（including severe wind speed）.
