摘要
以湖南工程学院体育馆屋面雨水排水系统为工程背景,对其临界降雨强度和临界重现期进行计算分析,提出了一种屋面雨水排水系统的分级分梯次排水型式,可以达到重现期的合理选择并取得良好的经济效果.
Taking the gymnasium roof rainwater draining system in Hunan Institute of Engineering as the engineering background, the critical rainfall intensity and critical recurrence period are calculated and ana- lyzed, a kind of roof rainwater draining system of graded echelon drainage patterns is proposed. The return period reasonable choice and a good economical effect are achieved.
