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.
