利用FORTRAN编程进行水闸泄流计算应用

Calculation of Water Gate Leakage Flow through FORTRAN Programming

某一等枢纽工程设计洪水、校核洪水洪峰流量分别为59700m3/s、67100m3/s,峰高量大。为满足工程运行要求,泄水建筑物共设置了15孔泄洪闸、5孔冲砂闸和1孔围堰改闸。水闸堰型均采用宽顶堰,孔宽不同,堰顶高程各异。现有泄流计算程序多针对单一堰顶高程设计,本工程并不适用。多闸孔、多堰高组合水闸泄流计算是一件繁琐的工作,利用Fortran编写的小程序计算给实际应用带来了极大便利。本文介绍了程序编写的具体过程,并结合具体工程应用实例对程序进行了验证。

One level I hinge project designed flood and checked flood peak flow capacities are respectively 59700 m3/s and 67100 m3/s, and the peaks are high with large volume. In order to meet requirements of project operation, the water leakage buildings are provided with 15 hole flood discharge gates, 5 hole scouring sluice gates and 1 hole cofferdam changing gate. The water gate dam shape has wide top dams with different hole widths and various dam top elevations. Existing leakage flow calculation programs are excessive aiming at single dam top elevation design, and the project does not apply the program. Multi-gate hole and multi-dam height combined water gate leakage flow calculation belongs to fussy work, and small-program calculation compiled through utilizing Fortran brings great convenience to practical application. The paper introduces the concrete process of compiling the program, and combines application examples of concrete projects to validate the program.
