摘要
对于大型自流灌区来说,保证渠道的灌溉水位,就是保证灌区的灌溉效益,节约灌区的灌溉成本。结合众程灌区程道倒虹吸工程实例,通过对程道倒虹吸工程不同运行工况水力计算分析,了解倒虹吸实际运行水位差大于设计值的主要原因,并提出合理的处理措施,可为类似工程设计过程中有效地减少或避免该问题的出现。
For large-scale gravity irrigation district,to ensure the irrigation water level of the channel is to ensure the irrigation benefit and save the irrigation cost.Combined with the example of Chengdao Inverted Siphon Project in Zhongcheng Irrigation District,through the hydraulic calculation and analysis of different operating conditions of the inverted siphon project,the main reasons for the difference of actual operating water level of inverted siphon being greater than the design value were found out,and reasonable treatment measures were put forward,which could effectively reduce or avoid the occurrence of this problem in the process of similar engineering design.
