［摘要］以张家口崇礼地区某建设中滑雪场为工程背景，对此工程所在的复杂山地地形的风场进行了风洞试验和数值模拟研究。研究结果表明，在山脊等高风速区域，风洞试验和数值模拟两种方法获得的结果吻合良好；在山谷等背风低风速区域，由于试验测速设备的局限等因素，数值模拟结果明显地大于风洞试验结果。根据数值模拟获得的风场数据，结合当地的气象数据，对滑雪场的风场环境进行了评估，给出了索道不同位置日最大平均风速大于特定风速的超越概率，为滑雪场的缆车索道规划提供风环境参考数据。

Abstract:Based on the engineering background of a ski resort under construction in Chongli area of Zhangjiakou, the wind field of the complex mountainous terrain where the project is located was studied by wind tunnel test and numerical simulation. The study results show that the results of wind tunnel test and numerical simulation are in good agreement in the high wind speed area such as the mountain ridge. In the low wind speed area such as the valley, the numerical simulation results are obviously larger than the wind tunnel test results due to the limitations of test speed measuring equipment and other factors. According to the wind field data obtained from numerical simulation, combined with local meteorological data, the wind field environment of ski resort was evaluated, and the probability of exceeding the maximum average wind speed in different positions of cableway was given, which provided wind environment reference data for the planning of cableway of the ski resort.

Keywords:complex mountainous terrain; wind field; wind tunnel test; numerical simulation
