研究倾斜底坡引起的溃坝问题。在底坡可变、完全透明的水槽中 ,垮坝产生牛顿流体流。用超声波和图像分析法精确研究给定横坐标的水位和波前的演变。粘滞流态的纳维尔 -斯托克斯方程和连续方程可用无量纲形式表示 ,并用一维浅层水流逼近法加以解释。试验与理论成果非常吻合。 Study the slope failure caused by slopes. In a variable, fully transparent sink, the collapse produces Newtonian fluid flow. Accurately study the evolution of water level and wavefront at a given abscissa using ultrasound and image analysis. The viscous fluid Navier-Stokes equations and continuous equations can be expressed in dimensionless form and can be explained by the one-dimensional shallow water flow approximation method. Experiment and theoretical results are very consistent.
