摘要
寒冷地区防渗渠道冻胀破坏是渠道设计中需要解决的重要问题之一,对于灌区末级小型渠道,一般采用“U”型断面型式,既能增强渠道的抗冻胀能力,也具有较好的水力特性。以伊犁河谷南岸灌区末级渠道为例,从灌溉工作制度、流量计算、断面比选、结构布置、抗冻胀设计等方面对“U”型渠道进行设计分析,并拟定适宜的抗冻胀措施。
Frost heave damage of anti-seepage channels in cold areas is one of the important problems to be solved in the design of channels.For small channels at the end of irrigation area,U-shaped section type is generally adopted,which can not only enhance the frost heave resistance of channels,but also have better hydraulic characteristics.Taking the Last-Level Canals in the Southern Bank Irrigation District of the Ili River Valley as an example,design and analysis of the U-shaped canal were carried out in terms of irrigation working system,flow rate calculation,cross-section selection,structural layout,and frost heave resistance design,and appropriate frost heave resistance measures were proposed.
