Abstract

A 3.3471 power function shaped open channel water conveyance cross section and its hydraulic optimal cross section solution method are disclosed. That cross section is y=a | x | 3.3471 power functionshaped cross section. The method comprise the following steps: 2, solving the hydraulic element of the cross section of the open channel; 3, establishing a hydraulic optimal cross-section model of theopen channel; 4, describing the wet circumference of the cross section of the open channel by adopting a Gaussian hypergeometric function expression; 5, solving the optimal solution of the hydraulicoptimal cross-section model; 6, solving that exponent of the power function when the water conveyance cross section of the power function shape open channel has the maximum overflow capacity. The invention can find out the maximum overflow capacity of the parabolic open channel section when y=a | x | k when k is a value, improves the hydraulic characteristics of the parabolic open channel section,increases the water conveyance capacity and reduces the construction cost of the open channel.

Description

technical field [0001] The present invention relates to a power function-shaped open channel water delivery section and its hydraulic optimal section solution method, specifically a 3.3471 power function-shaped open channel water delivery section and its optimal section solution method, belonging to irrigation area water delivery channel planning Design technology field. Background technique [0002] The optimal hydraulic section is a section with the largest flow rate when the flow area is given, or the section with the smallest flow area or wetted area when the flow rate is given, also known as the optimal hydraulic section. The known hydraulic optimum section of the trapezoidal channel is (where b is the bottom width, h is the water depth, and m is the slope coefficient). [0003] Scholars have been constantly exploring new channel cross-section forms in order to achieve the maximum flow capacity under the same area. Scholars generally believe that power function-shap...
