水利枢纽对水文水力特性的影响分析

Analysis of Influence of Water Conservancy Project on Hydrological and Hydraulic Characteristics

针对水利枢纽建设对坝区周边水文情势的影响具有不确定性的问题,以某地水利枢纽A为对象,借助非恒定流方程以及水利枢纽A的水文实测数据,提出一种基于非恒定流运动方程的新的水力特征判别方法,解决了水利枢纽对水文水力特性的影响难以预测的问题,实现了对水利枢纽水文特征进行分析预测的结果。结果表明,该方法不仅可以预测水波类型,还能够准确描述坝区流量特征,研究结果可应用于水利水电领域。

The problem of uncertainty in the impact of the construction of a water conservancy hub on the hydrological situation around the dam area is addressed. In this paper, a new hydraulic characteristic discriminant method based on the non-constant flow equation of motion is proposed with the help of the non-constant flow equation and the hydrological actual measurement data of hydraulic hub A. This method solves the problem that the impact of the hydraulic hub on the hydrological hydraulic characteristics is difficult to predict, and achieves the result of analyzing and predicting the hydrological characteristics of the dam area. The results based on the study of hydraulic hub A show that the method can not only predict the water wave type, but also accurately describe the flow characteristics of the dam area, and the research results can be applied to the field of water conservancy and hydropower.
