寒区复式输水渠道冰盖厚度变化特征模型试验研究

Model Test Study on the Variation Characteristics of Ice Sheet Thickness in the Compound Water Canal in Cold Region

随着经济社会的发展,寒区冰盖输水得到广泛运用。利用模型试验研究的方法,对输水渠道冰盖厚度变化规律进行研究。根据研究解困,推荐采用复式断面滩地部分低流速输水,促进冰盖的形成和加厚,以利于渠道运行安全。此外,基于试验数据给出了静水和动水条件下复式断面渠道冰盖厚度的计算公式,具有一定的实际应用价值。

With the development of economy and society, ice sheet water transportation in cold regions is widely used. The article uses the method of model test research to study the variation rule of ice cover thickness in water conveyance channel.According to the research to solve the problem, it is recommended to adopt the low-velocity water conveyance in part of the intertidal area with multiple sections to promote the formation and thickening of the ice sheet and facilitate the safe operation of the channel. In addition, based on the test data, the calculation formula of the thickness of the ice cover of the double-section channel under the conditions of static water and dynamic water is given, which has certain practical application value.
