摘　　要：通过设计实例,介绍了用于土壤侵蚀室内模拟试验的小型冲蚀水槽的设计方法。该试验装置可用于土壤侵蚀的填土冲蚀试验、薄层水流的水流特性试验和薄层水流的夹沙输沙试验,并且可以进行绿篱拦挡条件下的浅沟侵蚀试验。试验坡度可在1°、5°、10°、15°、25°调节,冲水流量在0～0.2m3/min可调,泥沙浓度在0～100gL可调。该试验装置的设计可为土工试验设计大型冲蚀水槽和更小型的冲蚀水槽提供一定的设计思路,从而更好地为土壤侵蚀的室内模拟试验服务。Method of mini-type flume for indoor simulation of soil erosion was introduced by design.This experimental equipment could be used for filling erosion experiment,flow characteristics experiment and of sedimentation of sheet flow,and ephemeral gully erosion experiment with hedgerow.Gradient could be adjusted in 1°,5°,10°,15°,and 25°.Glow adjustment range was 0-0.2 m3 min.And sediment concentration adjustment range was 0-100 g L.Experimental equipment can provide some design ideas to design for large-scale erosion and smaller erosion flume of soil engineering experiment design,and provide better service for indoor simulation of soil erosion.
