采用Lane平衡关系定义稳定河道,分析河道整体不稳定的影响与原因;分析蜿蜒河湾河岸冲刷特性,定义河道局部不稳定中的河岸冲刷与崩岸,对河岸冲刷动力与崩岸进行分类。
The influence of the instability of the whole river course is analyzed by using the Lane balance relationship. The erosion characteristics of the meandering river bank are analyzed. The erosion and bank collapse of the bank in the local instability of the river course are defined. The scouring power and bank collapse of the bank are classified.
