浅析格田淤区均匀沉沙的控制条件

Analysis on Control Conditions of Sediment Uniform Silting in Rectangle Fields

本文对一些引黄放淤实际工程进行了分析，论述了格田内泥沙运移沉积的特点与影响沉淤效果的因素。同时根据格田区内水沙运动特点和泥沙质量守恒原理，探讨了影响泥沙均匀落淤的格田流量、断面尺寸和退水口水位的控制条件。

Some engineering practices from the Yellow River have been expounded in this paper, and factors affecting silting quality have also been pointed out according to analysing some silting works. Three control conditions such as discharge,size of cross section and tail water level for uniform silting in the rectangle fields have been investigated by the authors based on transportation characters of flow and sediment, and conservation principle of sediment mass.
