Discussion of planned route and analysis of expected benefits of the Songliao Canal
This paper takes the Songliao Canal as the object,examining its strategic positioning,design throughput capacity,recommended route,and shipping comparative advantages,and conducts a comprehensive analysis of the positive effects of the canal after its completion from multiple environmental elements.The results conclude that the promotion of the Songliao Canal project is of great significance for accelerating the Northeast Sea-Land Integrated Transportation Corridor,serving as a powerful engine to boost the economic takeoff of Northeast China.The Songliao Canal is a constrained waterway.With full consideration of constraints such as river topography,route alignment,and construction difficulty,the planned waterway grade of the Songliao Canal is initially designed as Class Ⅱ,with the cascade locks in the connecting sections designed as Class Ⅰ double-line locks for inland waterway.The water transportation comparative advantages of the canal construction are significant,and it has played a good role in the environmental comprehensive benefits of nitrogen oxides,nitric oxide,particulate matter,sulfur dioxide,and carbon dioxide.Preliminary directions for tackling fundamental theories and key technologies in cross-basin canal construction have been proposed,encompassing canal section design,water and sediment regulation at tributary confluences,deep excavation and dredging of mountain passes,navigation safety assurance for combined river-sea transportation,ecological and safety assurance,and the establishment of a construction technical standards system.
