头屯河水库坝前冲沙漏斗及泄空冲沙的初步探讨

介绍了河流上建造水库形成淤积的原因及水库淤积的形态和特性，进而引入了水库排沙的一些方法，并描述了头屯河水库在没有进行泄空冲沙前的淤积形态及相关特征。研究和分析了坝前冲沙漏斗的形态及特征，其中包括冲刷坑深度和水下休止角等漏斗特征的确定。并根据这些淤积形态和漏斗特征，以及水库实际冲刷的形态和过程，建立了溯源冲刷的物理图形，找出适合溯源冲刷纵向冲刷长度估计的计算公式，并对头屯河水库冲刷长度进行了验证。

Toutun River Reservoir Upstream Flushing Funnel and the Emptying of the Initial Flushing

This paper describes the construction of reservoirs on the river silt formation of the reasons for the reservoir sedimentation and the shape and characteristics, the introduction of the reservoir desilting some of the ways and describe the first Toutun River Reservoir in the absence of a flushing air vent before the deposition patterns and related features. Research and analysis of the upstream flushing funnd shape and characteristics, including scouting hang rest angle and depth of the underwater features such as the determination of the funnel. According to the deposition and funnel shape and characteristics of the reservoir and the shape and the actual erosion process, a source scouring the physical graphics, find the fight fit for origin scouring vertical scouring the formula for calculating the estimated length, the Toutun River Reservoir and the first to scour the length of the verification.
