典型河段悬移质泥沙模拟方法研究

河流上修建的水利工程改变了原有河道水流泥沙的运动形式,而泥沙含量众多的悬移质泥沙往往影响着工程或河道的淤积状况,只有深入研究悬移质泥沙的运动形式,运用不同方法模拟河流悬移质泥沙对河道、水库等水利工程的影响,重现河流泥沙运动规律,揭示出悬移质泥沙对工程的影响机理,探求出减少泥沙侵害的技术途径。本文以模型试验设计的最新成果,运用模型试验方法和数学模型计算方法,并结合理论分析和模型试验,研究了天然河道典型河段悬移质泥沙冲淤问题,为解决工程泥沙问题探求一条可靠的途径。

Research on the suspended sediment simulating method in typical reach

The hydraulic engineering on river has changed the movement of flow and sediment in river,enormous suspended sediment has affected the deposition for the hydraulic engineering or river.Therefore,we only deeply study the movement of suspended sedement,simulate the effects with the suspended sediment to the river,reservoir and the hydraulic engineering by different method,to reappear the movement regular of sediment in river,to discover the influence mechamism of suspended sediment to the engineerings,to research the technical solution ways to reduce the sediment encroachment.In this study,physical model experiment and mathematical model have been used for studying the deposition of suspended sediment in typical reach river.
