摘要
以三峡为中心的长江中下游防洪调度系统需建立三峡库区和坝下游洪水演进数学模型。根据该系统的特点，将模型分解为三峡库区和坝址至湖口两大子系统，采用水文学方法进行洪水演进计算。经１９８１年、１９８３年等典型年洪水资料的检验，成果精度较高。引进计算机辅助计算技术。
In this paper, a mathematical model of flood routing for Three Gorge Reservoir centered flood control system is developed. The system is decoupled into two subsystems, namely the upper dam site subsystem and the dam site Hukou subsystem, according to its nature. The flood routing is carried out with hydrology methods. Tested with observed data of 1981 and 1983 flood events, it appears that the model holds satisfactory accuracy. The model also has advantages over past models with the introduction of computer aided techniques.
