| 摘 要： | 针对黄土高原坡面水力侵蚀调控实体模拟试验中存在验证不充分的问题,利用黄土高原小流域水力侵蚀调控实体模拟试验理论与技术,设计黄土坡面水力侵蚀比尺模拟试验,并对其进行验证。结果表明:在正态条件下,满足几何、降雨强度、入渗、径流运动、输沙、床面变形等相似条件下所建造的坡面模型;在试验条件下,虽然与模型原型流型有所偏离,但降雨、径流流态、平均流速、阻力系数、汇流过程、产沙、输沙及床面变形是基本相似的。表明该方法可以作为坡面治理水土流失、优化治理方案,寻求水土资源高效利用措施的工具。

| Abstract: | This paper introduced the water erosion scale simulation experiment on the loess slop,further verifying experiments were conducted on the similarities of the runoff and erosion processes.Based on the theories of the small watershed simulation experiment,a design method and verification of water erosion simulation experiment were given.The results showed that: the undistorted sloping model was similar to the antetype in the rainfall,the flow rate processes,mean velocity,runoff depth,drag coefficient,sediment... |
