河流结冰对电厂取水的影响

The Influence of River Freezes on Water Intake of Power Plant

西北地区取用地表水作为电厂供水水源,都存在有三防(防冰、防沙、防水草)问题。本文根据多年来部分工程的调查及实地观测资料,对河流结冰过程、冰情演变和冰流量、冰厚的估算方法,以及目前电厂所采取的防治措施作了分析研究,提出了解决取水口结冰问题的途径。

There are three problems such as ice prevention,sediment prevention,as well as aquatic weed prevention by taking surface runoff as water supply source for power plant in north-west area.On the basis of investigation and field observation data of some projects for years,the paper discussed and analyzed the freezing course and ice evolution,as well as estimation methods of ice quantity and ice thickness,and the current ice prevention and control measures adopted in power plant,then provided a solution to ice freezing at water intake.
