| 摘要: |
| 灌区排水工程主要是排除地面多余的水，降低地下水位，调节土壤水分，以达到实现农业稳产、高产和土壤改良的目的，其任务就是为作物正常生长创造良好的水土环境。灌区排水干渠的设计直接影响到排水工程的效益与成败。排水干渠设计要确定农田排水标准、排水范围及排水要求，规划好排水分区和排水方式，关键是要做好规模论证，其次是选择好排水出路和容泄区，然后再进行渠道纵横断面设计和建筑物设计。鉴于这方面的文章著述不多也还不够详细，本文以新疆某排水干渠设计为例，讲述了排水干渠工程规模论证的思路与方法，以供专业技术人员直接参考应用。 |

| Abstract: |
| The main purpose of drainage engineering in irrigated areas is to remove excess water from the ground, lower the groundwater level and regulate soil moisture, so as to achieve stable agricultural yield, high yield and soil improvement. Its task is to create a good soil and water environment for the normal growth of crops.The design of drainage channel in irrigation area directly affects the benefit and success of drainage project.The design of main drainage channel should determine the drainage standard, drainage scope and drainage requirements of farmland, and plan the drainage zoning and drainage mode. The key is to do a good demonstration of scale, then choose the drainage outlet and drainage area, and then conduct the design of vertical and horizontal sections of channels and buildings.In view of the fact that there are not many and detailed articles on this subject, this paper, taking the design of a drainage trunk canal in xinjiang as an example, describes the ideas and methods for the demonstration of drainage trunk canal project scale, so as to provide direct reference and application for professional and technical personnel. |
