摘要:
水土流失观测人工泥沙样品误差较大，因此样品均匀是提高观测准确性的关键。该文在已研制的可移动径流观测装置的基础上，通过对其泥沙混合装置中关键参数的实验测定，确定泥沙混合效果最佳条件下的混样桶高度和直径，以此实现高混合度泥沙样品的获取。结果表明：一级分流装置在高度H150 mm×直径Φ200 mm时混合效果最好，样品误差小于16%；二级分流装置在高度H40 mm×直径Φ60 mm时效果最好，样品误差小于7%。通过设定分流装置的高度和直径，可显著提高径流泥沙混合效果，此研究为提高可移动径流观测装置的观测精度提供了参考。
Abstract:
The observation error of soil loss by water erosion was high under artificial method, hence well mixed sediment in runoff is the dominant process of runoff sample collection. We developed a movable runoff collector. In order to collect a well mixed sediment sample, the parameters of runoff sediment mixing component of the equipment were tested, thereby the optimal height and diameter of the mixing barrel were confirmed. Results showed that sediment in runoff was best mixed in the first split barrel with the height 150 mm (H150) combined with the diameter 200 mm (Φ200). The sample error was less than 16%; and the height 40 mm (H40) combined with the diameter 60 mm (Φ60) of the second split barrel had the optimal mixing effect of sediment in runoff, whose error was less than 7%. The mixing effect of sediment in runoff could be greatly enhanced under an appropriate height and diameter of the mixing barrel. This measurement provided good parameters for the design of equipment for mixing sediment in runoff.
