摘要
本文选择荆江卵石夹沙河床及沙质河床的重点浅滩河段,在分析河床演变规律及浅滩成因的基础上应用文献（1）建立的二维动床数学模型,进行了不同组次来水来沙水文年的多个整治方案的数值试验,给出了荆江重点浅滩河段现状整治原则及整治工程的初步布置。
The typical Shoal reach of gravel-sand bed and sand bed on Jinjiang river were selected in this paper. Based on analyses of fluvial process and the reason of the shoal defomation, the 2-D movable- bed mathematical model that was established in reference (1) were applied. Many kinds of regulated layouts with different water and sediment hydrologic year were numerically tested. The regulated principle and the regulated engineering prelininary layouts of the typical shoal on jinjiang river were presented.
