摘要
人工降雨模拟装置具有缩短试验周期、克服实验场地限制和加速雨水入渗进程等优点,对农田水利、土木工程和矿业工程等研究领域都具有重要意义。文章简要介绍了目前国内外人工降雨模拟装置的发展趋势,重点评述了具有代表性的降雨模拟装置的系统组成、率定方法和工程应用进展,并探讨了其存在的问题。通过分析可知:喷嘴式人工降雨模拟装置应用最广,悬线式运用较少,管网式造价相对较低;人工降雨模拟装置的降雨强度率定方法常选用接流法,降雨均匀性率定常采用K值法,雨滴直径率定常运用色斑法,雨滴终点速度率定采用修正的沙玉清公式较为精确。
Artificial rainfall simulation device has shorten test cycle and overcome the limit of space and speed up the rainfall infiltration process and other advantages,rainfall in civil engineering,water conservancy and industrial and mining areas,such as engineering into infiltration, soil erosion, soil and water conservation arid rainwater set storage research has an important significance. p Brief introduction of the current domestic and international artificial rainfall simulation device development trend, this paper reviewed the development tendency of the rainfall simulation device system, calibration method and engineering application development, and pointed out the existing problems and solutions.Through the analysis, we knew that： nozzle type artificial rainfall simulation device is used most widely and wire suspension type to use less,pipe network construction cost is relatively low;artificial rainfall simulation device of rainfall intensity calibration method are often used in welding current method,uniform rainfall rate constant byKvalue method, raindrop diameter rate constant transport stain method, the raindrop terminal velocity determined by employing modified Sha Yu-qing formula is more accurate.
