摘要:
通过多次筛选试验研制出的单喷头变雨强模拟侵蚀降雨装置，以250余次的性能检测试验的结果表明：①该装置的有效模拟降雨面积为20～40m2；②降雨强度I与供水压力P的关系为I=13.017P1.456，r=0.978；③降雨均匀系数K≧0.80；④雨滴动能E，尺度参数a和中数直径d50%与供水压力之间的关系分别为E
Abstract:
The modeling erode rainfall device by using moni-spray gun to change rain intensity has been made through many times select experiments. More 250 times experiment resultsshowed that the device has an area of 20~~40m2 supplyed for efficient rainfall formed. The reIation between rainfall intensity I and supplying water pressure P is as follows: I=13.017P1.456,r=0.978.The rainfall equality coefficient K≧0.80.The rainfall motive energy E, the size a and the med direction d50% is respectively related to P as follows: E=6.374P0.459,r=0.928,a=0.919P0.259,r=0.909,d50t=0.856P0.258,r=0.880.
