| 摘 要： | 水平畦田较宽，采用一般进水口哨由于未考虑水流横向扩散作用而容易造成灌水不均或深层渗漏，针对这一实际问题，提出“侧堰式田间进水口”这一概念。通过建立明渠恒定变量流模型，研究了该进水口的设计原理，并利用计算机进行设计，最后，通过实际应用和设计实例验证了设计方法和该进水口的优越性。

| Abstract: | The non-uniform irrigation and deep percolation could be produced in border irrigation because of the wide border and unconsidering horizontal dispersion of field flow of the normal intake. The side weir field intake concept is presented. The design principle of the intake is studied by building an open channel stable and non-uniform flow model. The computer can be used for designing the intake. The advantages of the intake and design method are proved by practice application and design study case. |
