摘　　要：首先介绍了小型自排沉沙池的工作原理与工作过程,然后以物理模型对小型自排沉沙的水力学特性进行试验研究,通过试验资料深入分析了小型自排沉沙池内水流的流态特征,流速分布等水力特性。试验研究旨在为进一步研究小型自排沉沙池沉沙工况提供依据。In this paper, after the introduction of small size automatic flushing desilting basin of the working principle and working process, we studied the hydraulic characteristics by means of the physical model. In accordance with test data we also analyzed the water flow pattern, velocity distribution, and other hydraulic characteristics. This study is aimed at providing the basis for further study on small size automatic flushing desilting basin.
