摘　　要：利用风资源评估软件Meteodyn WT分别模拟京沪高铁沿线江苏段大胜关43个站点和阳澄湖23个站点2016~2018年瞬时风速数据,分析2地区风况特征,为京沪高铁安全行车、防风设计及优化站点布局提供依据。研究结果表明:2地区大风发生频率峰值均在下半夜,并且午后大风波动显著,秋季尤为明显;受气候和地理环境等影响,春季、秋季分别是大胜关和阳澄湖强横风高发季节,其中大胜关沿线在日出至正午时段易受强横风的影响,阳澄湖则需重点关注区域Ⅰ沿线运行;大胜关沿线在站点1~5和12处增设监测站点,并在站点1~5南北侧设置挡风墙,除站点13~17和32~36之外北侧亦需挡风墙。阳澄湖沿线合理布设站点,并在北侧设置挡风墙;高铁沿线在沿江、湖泊等地区切变指数小,风速大,易受强横风影响,而在平原、山地等粗糙地区则相反。The wind resource assessment software Meteodyn WT was used to simulate the instantaneous wind speed data of 43 stations at Dashengguan and 23 stations at Yangcheng Lake along the Jiangsu section of the Beijing-Shanghai high-speed rail line from 2016 to 2018,analyzedthe characteristics of the wind conditions in the two regions to provide a basis for the safe driving,wind-proof design and optimization of the station layout of the Beijing-Shanghai high-speed rail.Research shows that the peak frequencies of strong winds in the two regionsare in the second half of the night,and the high winds fluctuate significantly in the afternoon,especially in autumn.Affected by climate and geographical environment,spring and autumn are the seasons of strong crosswinds at Dashengguan and Yangcheng Lake respectively.Among them,the Dashengguan line is vulnerable to strong crosswinds from sunrise to noon,and Yangcheng Lake needs to focus on the operation along the area I.Additional monitoring stations will be added at stations 1~5 and 12 along the Dashengguan Pass,and windbreak walls will be installed on the north and south sides of stations 1~5.In addition to stations 13~17 and 32~36,windbreak walls are also required on the north side.Reasonably arrange stations along the Yangcheng Lake,and set up windbreak walls on the north side.Along the high-speed rail,the shear index is small and the wind speed ishigh in areas such as rivers and lakes,which are susceptible to strong crosswinds,while the opposite is true in rough areas such as plains and mountains.
