摘要
通过试验研究群坝局部冲刷问题 ,对群坝和单坝的水流现象进行了比较 ,分析了群坝局部冲刷与单坝局部冲刷的区别以及水流、坝距、坝长等因素对群坝各坝坝头局部冲刷深度影响 ,并根据试验资料提出了冲深计算公式。
Based on test studies on local scour of spur dikes group, flow pattern around spur dikes group is compared with that around the single dike. The difference of local scour between them is discussed and the influence of some factors, such as flow, distance between dikes and length of dikes, on their local scour depth is analyzed. Finally, a formula for scour depth is pressented from test data.
