| 摘 要： | 随机水力学是水力学研究的一个新发展。本文应用确定性模型与随机模型相结合的方法,对明渠非恒定渐变流的计算进行了研究。采用Saint Venant方程组为系统模型,但对系统的输入如明渠的糙率、过水断面、水力半径等,则采用适当的随机模型,产生的输出(流量、水位随时间和位置的变化)是随机性的、本文以柘溪水电站下游河道作为实例,用计算机进行了计算,并与实测结果作了印证。

| Abstract: | Stochastic hydraulics is a new development in the research of hydraulics. By coupling a stochastic model with a deterministic model, the computation of unsteady open channel flow is studied. Saint Venant equations are used as the sys -tern model. We use stochastic models for the inputs including roughness, cross-section, hydraulic radius and so on. The outputs of discharge and water level varyingwith time and location are stochastic. An unsteady flow in the downstream ofZhexi Water Power Station is calculated by this method as above, and the resultsare compared with the observed data. |
