铁路选线设计,用交付运营后第十年的运量作为设计的依据,用它来定铁路等级,定设计能力,计算运营费和工程费,综合选择各种方案,是从苏联学来的。这个运量在初步设计之后15年以上,即相当于三个五年计划以后的事情,30余年的设计经验证明,它的准确程度是很差的,与实绩对比,偏大很多,有的铁路大几倍至十几倍,用这样一个难以确切数字作为设计的基础,本身就缺乏科学的根据,许多事实证明。这是造成铁路投资增大甚至浪费的主要原因之一。
The design of railway route selection is based on the design of the tenth year after the delivery of the operation. It is used to determine the railway grade, design capability, calculation of operating expenses and construction costs, and comprehensive selection of various options is learned from the Soviet Union . This traffic is more than 15 years after the initial design, which is equivalent to three five-year plan after the event, more than 30 years of design experience has shown that its accuracy is very poor, compared with the actual performance, much larger, and some railways Several times to ten times as many times. With such an inaccurate number as the basis for design, there is a lack of scientific basis in itself. Many facts have proved. This is one of the main reasons for the railway investment to increase or even be wasted.
