摘要
运用四点偏心preissmann格式将圣维南方程组离散并线性化,得到的线性代数方程组应用追赶法模型进行求解,并将该模型应用在3种概化河网算例中进行检验计算,结果良好。证明该模型应用在包含分汇流、溢流坝或湖泊集水等复杂内节点的河网中的可行性和通用性。
The paper introduces one method that adopts 4- points eccentric preissmann scheme with time and space to disperse and liberalize the Sait-Venant equation group and applicates chasing method model to solve the last linear algebra equation; then it is applied to three typical calculation examples that include several complex inner nodes such as distributary and conflux, weir, eatchmentand and obtain good result, This proves that it is viable and all-purpose.
