摘要
采用正交曲线网格生成技术建立一种明渠导流双戗堤立堵进占截流的数学模型。该模型可精细模拟各种截流工况下龙口各水力参数的变化规律以及导流明渠的流态变化和过流能力。通过对三峡水利枢纽大江截流水力要素的数值预测，并与三峡水利枢纽二期围堰导流的模型实验资料进行了比照，结果吻合良好。该数学模型可为水利水电截流工程制定施工方案提供依据。
The technique of orthogonal curve-linear grid generation is used to establish the math-ematical model for the open diversion channel with two embankments in river blocking. Thismodel can also be used to simulate the varying laws of hydraulic parameters under the variousworking conditions in river blocking, variations in flow patterns and passing flow capacity of thediversion open channels. This model is also used to predict the numerical values of hydraulic ele-ments in the blocking of the Yangtze River of water resources junction works in TGP and tocompare model test data of the embankments of Phase Ⅱ of water resources junction works inTGP with the results in good agreement. This mathematical model can also provide the base forpreparing construction programme for water resources works and hydroelectric power engineeringin the river blocking.
