摘要
本文对基于平面二维水流数学模型的有限元离散求解方法进行了研究探索，并应用于某电站行洪论证与河势稳定评价，模拟计算了工程建设前后坝厂区河道水流流速、水位、流态的变化情况，对防洪及河势稳定影响进行了分析。计算结果与实际水流流态相符，能反映河流动力学的基本规律，验证了采用计算方法的可靠性。
A finite element discrete solving method on the base of two - dimensional flow mathematical model is studied and explored in this article, this method is applied to demonstrate draining flood and evaluate river potential stability of a hydropower station, flow velocity、water level、changes of flow pattern at plant area behind dam before and after project construction is simulated, influence of flood control and river potential stability is analyzed. The calculation result is accordant with real flow pattern, which reflects that the basic law of river dynamics and verifies that the adopted calculation method is credible.
