宁夏引黄灌区唐徕渠高地下水位渠段砌护方式研究

Research of Tanglaiqu Channel lining method in the high underground water level section in the irrigation area of Ningxia

水资源供需矛盾日益突出,对宁夏引黄灌区骨干渠道进行砌护改造,减少渗漏,减少渗透破坏,提高水利用系数是亟待解决的课题.对目前常用的几种砌护形式进行渠道渗漏量和地下水向渠道入渗量的对比分析,综合考虑防渗和稳定各方面因素,优选出适合唐徕渠高地下水位渠段的最优砌护方式.

In the increasingly serious imbalance between supply and demand of water resources environment, it is imminently to build backbone channel by laying bricks or stones in the irrigation area of Ningxia in order to reduce the leakage, reduce the seepage failure and improve the water use coefficient. In the base of contrasting and analyzing the seepage quantity and groundwater infiltration of the commonly used several kinds of protective structure of channel at present, considering seepage and stability and other factors the optimal way of building by laying bricks or stones to protect Tanglaiqu Channel can be selected when the Tanglaiqu Channel under the condition of high underground water level.
