摘要
文中介绍了4种长距离明渠输水常用的渠道运行的方式,上游常水位、中点常水位、下游常水位、控制容量运行方式。并结合实例对下游常水位和中点常水位运行方式进行计算,模拟非恒定流的典型数学模型,借鉴了特征线法,并用来计算不同的运行条件下的非恒定流过程。
The paper introduces 4 kinds of the common operation modes of long distance open channel water conveyance, including the operation modes of upstream constant water level, midpoint constant water level,downstream constant water level and the control capacity. Combining with the practical example, the paper calculates the operation modes of downstream constant water level and midpoint constant water level, establishes the typical mathematical model to simulate unsteady flow and calculates the unsteady flow process under the different operation condition referencing the characteristic line method.
