采用全沙动床物理模型试验，在验证试验基础上，模拟了各种可能出现的不利情况，研究永定河滞洪水库方案的可行性。分析方案实施前后，河道演变特点，为方案的设计及工程的维护提供了科学的定量参考数据。
Based on the verification test, all kinds of possible adverse conditions are simulated and the feasibility of the Yongding River detention flood reservoir project is studied. Before and after the implementation of the program was analyzed, the characteristics of the evolution of the river course provided scientific and quantitative reference data for the design of the project and the maintenance of the project.
