河床床面冲淤变化对渗渠产水量的影响

Influence on infiltration ditch water intake from the change of river bed condition

渗渠取水是一种传统的取水方式,其产水量会随着时间的推移而逐渐减少。影响渗渠产水量的因素是多方面的,河床床面冲淤变化对渗渠产水量的影响尤为突出。本文比较清水、浑水试验时的渗渠产水量,说明河床床面冲淤变化对渗渠产水量的影响,提出设计渗渠时应尽量将渗渠布置在水力条件良好的河段。本项研究成果可供实际工程参考。

Infiltration ditch for water intake is a traditional method of obtaining water. The amount of water obtained by infiltration ditch is decreasing as time elapsihg. A lot of factors have influenced on the amount of water by infiltration ditch water. The variety of river bed has a critical influenced for the water intake. The amount of water obtained by infiltration ditch was compared with clear water and muddy water experiment. The variety of river bed has an influence on water volume by infiltration ditch. Infiltration ditch should be set up in the better river section which has a better water condition that has been proposed in this paper. This research result can be referenced by real project.
