灌区提高渠系水利用率是农业节水技术的一个重要指标。新疆地处严寒地区,混凝土渠道在冬、春之交存在着严重的冻涨破坏。本文在揭示新疆混凝土渠道冻涨破坏机理———认为边坡板上切向冻涨力是导致渠道冻涨破坏的主导因素的基础上,提出一系列的防治方法,旨在为寒区灌区渠道维护提供参考。
Irrigation district to improve the canal water utilization rate is an important indicator of agricultural water-saving technology. Xinjiang is located in severe cold areas, concrete channels in winter and spring there is a serious freeze up the collapse. Based on the revelation of the mechanism of frost heave and collapse of concrete channels in Xinjiang - that the tangential frost heave force on the slope plate is the dominant factor that causes the channel to freeze up and destroy, a series of prevention and control measures are put forward, Maintenance for reference.
