AB - The influence of the surrounding building topography of the Datong-Xi'an  high-speed railway foundation on the wind environment and the thermal  comfort is studied, especially the outdoor wind environment and indoor  air-flow organization of the surrounding buildings are analyzed  numerically, and the building terrain and the indoor temperature and the  wind's speed distribution are systematically evaluated. The results show  that the surrounding terrain of the roadbed has a significant effect on the  wind environment of the site, affecting the natural ventilation in summer  and wind-proof and energy-saving in winter. The terrain surrounding of the  building in summer reduces the wind speed by 30.5%, and it increases in  winter by 31.6%; the wind speed in the indoor personnel activity area of the  building around the roadbed is less than 0.35 m/s, leading to a comfortable  body feeling.
