In basic equations of an unsteady flow consider just the energy loss due tothe cross section change. In an actual irregular channel, when the boundaryand the initial conditions are given, the real dam-break flood wave can beregarded as one dimensional flow. Using characteristic type difference schemethis one dimensional flow is simulated mathematically by electronic com-puter. The results including the calculated stage, discharge, and width of dambreak flood are well consistent with the field data. This result shows that ma-thematical model is a possible approach available for dam-break wave rese-arch. The inaccuracy of the schemed channel section from the original data maybe one reason characterizing a few improper results appeared in calculation.

本文在不稳定流基本方程中,仅仅考虑由于水流横断面变化引起的能量损失,用特征型差分格式,在给定的初始、边界条件下,将天然不规则河道的实际溃坝洪水波作为一维流考虑,借助电子计算机进行数学模拟。所获得的结果,包括计算水位、流量和溃坝洪水泛滥宽度等水流变量,与现场调查的资料比较,吻合较好。这一结果表明,数学模型在研究溃坝波方面是可行的办法。 河道地形资料概化中的误差,可能是计算中出现个别不合理结果的一个原因。 关于溃坝波有待进一步研究的课题,包括溃坝波二维数学模型以及在水库非常泄洪或自溃坝场合下过桥水流的数学模拟,等等。
