Study on Wind-Proof Effect and Stability of Windbreak Fence in Alpine Skiing Center

As a venue for the 2022 Winter Olympic and Paralympic Games, National Alpine Skiing Center is located on Xiaohaitou Mountain in Beijing’s Yanqing district, where strong winds occur frequently. To reduce impact of competition, windbreak fences have been installed ski area. determine effect stability beside slope alpine skiing center, numerical simulation method was used to study performance 3.7 m, 4.7 m 7.9 high wind barriers. According actual meteorological conditions, two kinds inlet speeds 10 m/s 33 were set. The results show that ambient speed maximum only small area near opening through fence. When m/s, most drainage areas behind barrier below 5 15 respectively, which significantly lower than incoming flow, protection obvious. at entrance height wind-proof windproof bars better bars. pressure top fence highest, also increases when increases. Under action speed, storm low.
