引黄灌区渠道防渗工程技术是常用的节水灌溉技术措施之一,其中混凝土护坡防渗采用较普遍,节水效益最为明显,在引黄灌区混凝土护坡渠道还具有输沙能力好且施工简单易行的特点。因此,在引黄灌区节水工程建设中广为应用。但在实际运行中,由于引黄灌区普遍地下水位较高,渠道混凝土护坡由于受渠道内水位变化的影响,护坡承受双向荷载作用较为明显,受力条件较为复杂及设计不合理和施工中一些问题等
Seepage control technology of canal irrigation in Yellow River Diversion Project is one of commonly used technical measures for water saving irrigation. Among them, concrete seepage control of concrete slope protection is more common and water saving benefit is the most obvious. Concrete retaining slope channel in Yellow River Irrigation District also has good sedimentation capacity and simple construction Easy to use features. Therefore, it is widely used in the construction of water-saving projects in Yellow River Diversion Area. However, in actual operation, due to the high groundwater table in the Yellow River Diversion Irrigation District, the influence of water level changes in the channel concrete revetment is more obvious, the stress conditions are more complex and the design is not reasonable and some problems in construction Wait
