| 摘 要： | 随着国民经济的发展和上海浦东新开发区的发展，长江口深水入海航道的选择与治理，已越来越多地引起人们的关注，长江口深水入海航道的选择基本上可以分为避开拦门沙和不避开拦门沙两类。本文根据长江河口的发育模式、河口延伸、汊道演变的规律、汊道的形态与水力条件，提出长江口拦门沙深水入海航道整治规划，近期以北槽－８ｍ航槽为宜，远期可逐步开发至－１２．５ｍ

| Abstract: | This way for regulating the deep seaward waterway in the Yangtze Estuary can be categorized into two :one is to go through the mouth bar, the other is to pass by it.This paper,according to the historical developing model of the estuary,the extention of the estuary,the principal of the bifurcation process as well as the form of the bifurcation and the hydraulic conditions,deals with the regulating alternative for the seaward waterway in the mouth bar area and points out an available alternative for the short-term regulation of -8m depth waterway through North Passage. It can be devecoped into -12. 5m depth gradually in the long-term plan. |
