摘要
结合紫坪铺水利枢纽工程的溢洪道挑坎特性,采用模型试验的研究方法,根据挑流鼻坎体型设计理论和它灵活性特点,应用CFX软件对挑流鼻坎体型进行了改进优化,以使挑流水舌分布更均匀、挑距更大和冲刷更小,并通过对水舌和冲坑特性的观测来验证改进结果。
The figure of trajectory bucket is improved and optimized by CFX software, with spillway trajectory bucket character of Zipengpu water complex, through model test, according to trajectory bucket figure design theory and its flexible character, for uniform distribution of trajectory nappe, big trajectory distance and small scouring. The improving effect is verified by the observation of water nappe and washout character.
