摘　　要：卢塞尔体育场作为2022年世界杯开幕式和闭幕式的举办地,是卡塔尔世界杯比赛期间最重要的球场之一。在对体育场建设位置地理、气候条件和屋面构造特征等因素分析的基础上,通过采用FLUENT软件对卢塞尔体育场屋面排水进行模拟分析。结果表明,当发生百年一遇降雨事件时,屋面内天沟最深处水深约为0.12 m,外天沟最不利水深约为0.15 m,均满足设计要求;末端沉箱内水深最深约为1.6 m,小于现状沉箱设计深度,可以满足屋面排水需求。对于超大型建筑屋面雨水排水,通过模拟验证了设计的可行性,也为大型屋面雨水排水设计提供了新思路。The Lussel Stadium, which has hosted the opening and closing ceremonies of the 2022World Cup, is one of the most important stadiums during the tournament in Qatar. Based on the analysis of factors such as geography, climate and roof structure characteristics, the FLUENT software was used to simulate the roof drainage of Lussel Stadium. When there was a hundred-year rainfall event, the deepest water depth of the inner gutter on the roof was approximately 0.12 m, and the most unfavorable water depth of the outer gutter was approximately 0.15 m, suggesting that the water depth of the gutter met the design requirements. The deepest water depth in the bottom collection box was approximately 1.6 m,which was less than the current design depth of the collection box and met the demand of roof drainage.For rainwater drainage of super large building roof, the feasibility of the design was verified by the simulation, which also provided a new idea for the rainwater drainage design of large roof in the future.
