摘要
宁夏灌区末级渠系面广量大,位于季节性冻土地区,渠道衬砌往往破坏严重,影响了正常的渠道输水和安全运行。本文在对灌区末级渠系现状全面调查的基础上,根据衬砌破坏程度对渠道的破坏类型进行了划分,对破坏原因进行了研究分析。研究结果可作为灌区渠道设计的依据,也可为灌区节水工程改造和渠道衬砌工程的建设提供技术支撑。
The end-canal system of Ningxia Irrigation with wide area and large amount is located in a seasonal frozen soil region, and then the damage of canal lining is sometimes serious and impacts the normal and safe operation of the water conveyance with canal. Based on a comprehensive investigation on the status of the end-canal system of the irrigation area, the types of the lining damages are classified herein in accordance with the damage degrees eoneemed, while the causation of the lining damage is studied and analyzed as well. The study result can not only make a technical basis for the canal design of the relevant irrigation area, but can also provide a technical support for the improvement of the water-saving project and construction of the canal lining project.
