Study on Fluvial Process and Regulations of Typical Shoal of Middle Yangtze River
Lu Yongjun1、 Liu Jianmin2
根据浅滩的形成条件及演变特征,长江中游浅滩可分为分汊段浅滩、顺直(微弯)过渡段浅滩和弯道复杂浅滩三类,分析了这三类浅滩的成因及演变规律。简述了荆江裁弯及葛洲坝水利枢纽的运用对重点浅滩航道的影响,提出了现状整治原则及整治工程布置的初步想法。
Based on analyses of fluvial process and the reason of the shoal deformation, the shoals of the middle Yangtze River can be divided into three kinds, i.e. the shoals of the braided reach, the shoal of the straight transitional reach and the shoal of the bend. The influences of cut-off of the lower reach of Jingjiang River and river bed evolution on the shoal due to the set-up of Gezhouba Dam are briefly presention. The regulation principle and the regulation engineering preliminary layouts of the typical shoal are discussed.
