中小河流推移质测验装置的设计与应用

Design and Application of the Bed Load Measuring Device for Medium and Small Rivers

摘要: 推移质运动极其复杂，且推移质泥沙又主要集中在洪水期间，因而推移质泥沙测验及其装置研制仍是一个世界难题和热点问题。本文讲述了一种适用中小河流推移质精准测验装置的设计，主要由推移质采集器、推移质校准器和船载联控支架等三部分组成，同时论述了推移质测验装置的具体操作和测验方法，可有效解决中小河流推移质“无法测、测不到、测不准”的难题，为新的水沙条件下河流推移质测验提供一定借鉴和参考。

Abstract: The bed load movement is very complex, and the bed load sediment is mainly concentrated in the flood period, so the bed load sediment measurement and device development are still a world problem and hot issue. This paper describes the design of an accurate bed load testing device for small and medium-sized rivers, the bed load testing device includes three parts: bed load collector, bed load calibrator and ship-borne joint control support. Meanwhile, it discusses the specific operation and testing methods of bed load testing device, which can effectively solve the problem of “no way to measure, no substance available for test and inaccurate test” in the bed load of small and medium-sized rivers and provide a certain reference for river bed load testing under new water and sediment conditions.
