摘要
弯道水沙的螺旋流运动特征是导致河流滩岸崩塌以及河道向弯曲形态演化的主要因素.从弯道水流的运动机理出发,运用数值计算手段对概化弯道流场进行模拟.通过计算,分析了不同弯道丁坝布设角度的水流运动特征,提出了较优的弯道丁坝的布设方式.
Spiraling flow movement characteristics of water and sediment in bends are the main factors which lead to river bank collapsing and the channel bending evolution.Based on the movement mechanism of bend flow,the generalized bend flow field was simulated using numerical calculation method.On this basis,an optimal layout of the spur dike in bends was presented by calculating and analyzing water flow movement characteristics in different layout angles of the spur dike in bends.
