In this paper, the effects of water on obstacles in dam-break flow for different angles of the inclined planes have been numerically examined. The presented computational data are compared with data from the experiment and computational simulation data of other authors. Good agreements between the obtained simulation results and measurement data demonstrate the satisfactory performance of the mathematical model and the numerical algorithm when reproducing a dam-break flow. Additionally, various problems were also considered: the effect of pressure distribution on the dam walls for different angles of the inclined plane. It was found that pressure distribution on the wall when the inclined angle $\gamma$ = 15° was almost two times more than without inclination. To reduce the shock pressure value a new form of obstacle was used. With a new form of obstacle, the maximum pressure value on the dam wall decreased more than three times.

本文通过数值研究了水在不同角度的倾斜面对溃坝水流障碍物的影响。将呈现的计算数据与来自其他作者的实验数据和计算模拟数据进行比较。获得的模拟结果与测量数据之间的良好一致性证明了在再现溃坝流时数学模型和数值算法的令人满意的性能。另外，还考虑了各种问题：对于倾斜平面的不同角度，压力分布在坝壁上的作用。发现倾斜角时壁上的压力分布$\gamma$= 15°几乎是没有倾斜时的两倍。为了降低冲击压力值，使用了一种新形式的障碍物。有了新形式的障碍物，坝壁上的最大压力值下降了三倍以上。
