一、前言设计一条成功的渠道,应该基本保证不冲不淤,为此,必须对渠道的耐冲流速与挟沙能力作专门研究;可是,目前在这两方面的研究工作还未达到令人满意的地步,鉴于西北灌溉历史较早,许多渠道经过长期使用,已趋于稳定,对于这些稳性渠道进行调查,总结其经验,分析其稳定因素,结合挟沙能力与耐冲流速的现有研究成果,制定黄土渠道断面设计方法,对于指导目前的生产是有一定作用的。二、陕西关中泾、洛、渭灌区黄土稳性渠道调查分析
I. Preface To design a successful channel, it should be basically guaranteed not to be washed or not to be silted. To this end, we must make a special study on the fast-flowing and sediment-carrying capacity of channels. However, the current research on these two aspects has not yet reached a satisfactory level Satisfied, given the earlier history of irrigation in the northwest, many of the channels have been stabilized over the long term, surveying these stable channels, summarizing their experience, analyzing their stability factors, combining the available sediment capacity with the current available velocity Research results, the development of loess channel design section, for guiding the current production is to some extent. Second, Shaanxi Guanzhongjing, Luo, Wei irrigation area loess stability channel investigation and analysis
