汉江是长江水系中一条重要的通航河流,全长1567公里,通航里程1313公里。位于中下游的襄樊至(氵利)河口段为游荡性河道,河床宽浅不稳,航道条件差,只能通航150吨级的船舶;(氵利)河口至汉口,可通航300～500吨级船舶。为改善襄(氵利)河段的通航条件,使之近期达到通航500吨级船舶的标准,襄(氵利)河段必须整治。本文主要依据修建丹江口水库后的实测地形资料,仅对襄(氵利)河段的演变特征、浅滩河段的分类以及整治宽度等,进行讨论。
Han River is an important navigable river in the Yangtze River water system with a total length of 1,567 kilometers and navigation mileage of 1,313 kilometers. The middle and lower reaches of the Xiangfan to (氵 利) estuary is a wandering river, riverbed unstable, poor waterway conditions, only navigation 150-ton ships; (氵 利) estuary to Hankou, navigable 300 to 500 tons Class ship. In order to improve the navigable conditions of Xiang River and make it reach the standard of navigating 500-ton ships recently, it is necessary to rehabilitate the Xiang River. This article mainly based on the measured terrain data after the construction of Danjiangkou Reservoir, only the evolution characteristics of the Xiang River section, the classification of the bank section and the width of remediation, are discussed.
