渠道均匀流水力计算优选法图解

本文提出一种用于渠道均匀流水力计算的新图解方法。新图解不仅较之现有的传统计算方法简化了计算,提高了计算精度,而且对渠道断面尺寸可择优采用。同时避免了现有计算方法中由于事先拟定渠底宽或渠水深使渠道断面有可能出现的过于宽浅或过于窄深的现象。

Optimiyatian Graphs far Hydraulic Computation Of Steady Uniform Flow in Conals

Opimization graphs Presented in this paper may be used in hydraulic computation of steady uniform flow in canals with reclangular trapezoidal, circular and U—shape cross—sections respectively, the accuracy of results obtained is higher, and the tine required is shorter than that obtained and required by conventional graphic methods, In addition, the graphs presented may allow the user to optimize his salution by suitable selection and avoid the canal designed to be too narrow or too shallow.
