摘　　要：柳江Ⅱ级航道作为西南水运出海北线通道的重要组成部分,但运力不足。根据整治河段自然资源分布、社会经济发展与工业布局现状及规划、航运发展前景对建设柳江Ⅱ级航道进行可行性研究。建立柳江Ⅱ级航道设计标准和设计原则,依据通航率和航道等级,提出一种计算航道尺寸的方法,并基于柳江Ⅱ级航道工程设计最低通航水位和河段分期水位-流量计算柳江Ⅱ级航道流量,根据Ⅱ级航道弯曲半径的要求及使用和维护的便利性,提出滩段航道线路方案,实现全长173 km的2 000吨级Ⅱ级航道建设,根据运量预测2025、2035、2050年货运量分别为2 670万、4 810万、6 500万t。The Liujiang classⅡwaterway is an important part of the northbound route of southwest water transport to the sea,but the transportation capacity is insufficient.The feasibility study on the construction of the Liujiang classⅡwaterway is carried out according to the distribution of natural resources of regulation river reach,the current situation and planning of social and economic development and industrial layout,and shipping development prospect.The design standards and principles of the Liujiang classⅡwaterway are built.A method for calculating the size of the waterway are proposed according to the navigation rate and the class of the waterway,and the flow of Liujiang classⅡwaterway is calculated on the basis of the minimum navigable water level and the stage water level-flow of the river section.The beach section waterway route scheme is proposed to realize the construction of a total length of 170 km and 2,000-ton level of classⅡwaterway according to requirements of the bending radius of the classⅡwaterway and the convenience of use and maintenance,inview of the freight volumes in 2025,2035 and 2050 are 26.7 million tons,48.1 million tons and 65 million tons respectively.
