据铁道部有关部门预测“七五”期间,铁路客货运量将增长到换算周转量达到14000亿吨。公里比1985年增长33%,到2000年,客货运量将分别比1990年增长78.6%和56.3%,这样繁重的运量是必促成机车车辆轴重的增加及列车对数的增加,这就意味着对轨道的负担与破坏力增加,因此在轨道的各个部分必须加强,本文单就加强轨枕的强度的问题作一探讨。
According to the prediction of relevant departments of the Ministry of Railways during the “Seventh Five-Year Plan” period, the passenger and freight traffic volume of the railway will increase to 1.4 trillion tons of converted turnover. Km, an increase of 33% over 1985; by 2000, passenger and freight traffic will have increased by 78.6% and 56.3% respectively over 1990 levels. Such heavy traffic will inevitably lead to an increase in the axle load of locomotives and an increase in the number of trains This means that the burden and destructive force on the track has increased and must therefore be strengthened in all parts of the track. This article addresses the issue of strengthening the strength of sleepers alone.
