一、水运工程经济分析的任务交通运输是国民经济发展的战略重点之一。各种运输方式如铁路、公路、水运、航空、管道等组成统一的运输体系。它们都有各自的特点和经济的使用范围。水运在运输体系中具有运量大、成本低、耗能省、投资少的特点,最适合于运输煤炭、石油、粮食、建材、矿砂等大宗散货;水运成本一般为铁路的1/3～1/5,为公路的1/8～1/20;内河运输每吨公里消耗的燃
I. Tasks of Economic Analysis of Waterway Engineering Transportation is one of the strategic focuses of national economic development. Various transportation methods such as railways, highways, water transport, aviation, and pipelines form a unified transportation system. They all have their own characteristics and economic use. Water transport has the characteristics of large transport capacity, low cost, energy saving, and low investment in the transportation system. It is most suitable for transporting bulk bulk cargoes such as coal, petroleum, grain, building materials, ore, etc. The cost of water transportation is generally 1/3 of the railway. 1/5, 1/8 to 1/20th of highway; consumption per ton-km for inland water transportation
