某灌区总干渠3^(#)退水闸设计研究

Study on the Design of NO.3 Discharge Sluice of Main Canal in an Irrigation District

灌区续建配套与现代化改造建设中,总干渠退水闸设计对工程安全运行具有重要意义。结合某灌区刁河总干渠3^(#)退水闸重建工程案例,了解工程概况,着重围绕结构设计、水闸水力计算、闸基渗流稳定计算及闸室稳定应力计算等几部分研究灌区大型退水闸设计的基本内容。完成了刁河总干渠3^(#)退水闸重建工程的复核及设计成果,可为类似灌区现代化改造提供参考。

In the construction of supporting facilities and modernization of the irrigation area, the design of the discharge sluice of the main canal is of great significance to the safe operation of the project. Based on the reconstruction project of Diaohe main canal NO.3 discharge sluice in an irrigation area, the general situation of the project is understood. The basic contents of the design of large-scale discharge sluice in the irrigation area such as the structural design, hydraulic calculation of sluice, seepage stability calculation of sluice foundation and stability stress calculation of sluice chamber are analyzed and studied in detail. The review and design results of the reconstruction project of NO.3 discharge sluice of Diaohe main canal have been completed, which can provide reference for the modernization of similar irrigation areas.
