浅析水利水电工程沉沙池泥沙沉降计算方法

本文对沙早水电工程沉沙池设计中最常用的泥沙沉降计算方法，准静水沉降法和一度流超饱和输沙法，从公式结构上进行了一定的分析研究，结果表明，在一定条件下，准静水沉降法之计算公式是一度流超饱和输沙法（不考虑水流挟沙能力）的一种近似表达式，可用来估算沉沙池内含沙量变化。

Simple study on calculation of sediment deposit in settling basin of hydraulic and hydroelectric engineering

The paper provides a study of the most widely used calculation methods of sediment deposition in settling basin of hydraulic and hydroelectric engineering. The methods mentioned above are quasic-still water deposit method and supersaturated sediment transport method in one dimension flow. The results of the study show that the quasic-still water deposit method is the approximate expression of the supersaturated sediment transport method in one dimension flow under given conditions (without consideration of sediment transport capacity),and can be used to estimate the sedanment change in settling basin.
