摘要
洪水极具破坏性,对溃堤洪水造成的堤后冲刷现象进行深入研究和内在规律探讨具有重要的理论和实践意义。文章以太子河本溪段河道为工程背景,利用物理模型试验的方法,对不同溃决水头高度下的冲坑形态进行试验研究。结论显示,冲坑深度和范围随着水头高度的增加而增大,但是水头高度与冲刷坑变化速率之间的关系并不明显。
Flood is very destructive.It is of great theoretical and practical significance to conduct in-depth research on the phenomenon of scouring behind the dike caused by the levee breach flood and to discuss the internal laws.The method of physical model test is utilized to carry out experimental research on the form of scouring hole at different levee breach water head heights based on the river course of Benxi Section of Taizi River as the engineering background.The results show that the depth and range of the scour hole are increased with the increase of the water head height,but the relationship between the water head height and the scour hole change rate is not obvious.
