| 摘 要： | 介绍了适于在室内进行土壤侵蚀模型试验的SX2002管网式降雨模拟装置和试验方法。率定试验的结果表明,雨强在1.2~4.0 mm/m in时,其雨滴中值粒径在1.2~2.0 mm之间,降雨动能与天然降雨接近,有效降雨均匀度超过80%。在SX2002管网式模拟降雨装置中,把雨强作为主要控制参数来实现降雨模拟的动能相似在实际操作中是方便可行的。 |

| Abstract: | The paper introduces SX2002 pipe-network-type precipitation simulation apparatus and a testing method of soil erosion model which is suitable for laboratory operation.The outcomes of calibration test show that when rainfall intensity is 1.2 ~ 4.0 mm/min and median particle diameter of raindrop between 1.2 ~ 2.0 mm,the kinetic energy of precipitation is close to the natural rainfall and the degree of consistency of effective rain is greater than 80%.During the practical operation,it is convenient and feasible to take the rainfall intensity as a key controlling parameter to achieve similar kinetic energy of precipitation simulation through the SX2002 apparatus. |
| Keywords: | soil erosion simulated precipitation controlling parameter calibration laboratory testing |
