摘要
为逐步改善农田的灌溉条件,把现有中低产田改造成为旱涝保收的稳产高产农田,山西省非常重视农村水利工程的建设。本文以2015年太原市小店区农田水利建设项目配套末级渠系工程为例,对其设计流量、渠道水力计算、纵断面设计、冻胀分析、防渗设计以及渠系建筑物设计作了简要介绍。末级渠道改造工程的实施能够提高水资源利用效率,提升小店区农业生产的经济效益,在很大程度上改善农田灌溉条件,有利于稳产高产农田的实现。
In order to improve the field irrigation condition and to transform the farmland from giving low and medium yields to giving stable, high yields irrespective of drought or water logging, Shanxi Province attaches great importance to construction of rural irrigation projects. The paper gives a brief introduction to its design discharge, canal hydraulic calculation, profile design, frost-heave analysis, seepage control design and structure design of the canal system taking the associated end stage canal system of the farmland irrigation project constructed in 2015 in Xiaodian District of Taiyuan City as an example. The rehabilitation of the end stage canal system helps to improve both utilization efficiency of water resources and economic benefits of agricultural production of Xiaodian District, so that the farmland irrigation conditions are improved to a great extension, helping implementation of the farmland with stable and high yields.
