三十多年来,铁路工程情况变化很大。五十年代,短短几年,全国分割的线路联成一体,新线直通西陲,不久,西南山区也修成路网初步骨架。这些巨大的成就,在解放以前,连作梦都想不到的。可是,六十年代迄今,造价、工期增为数倍,施工机械不断增加,生产率反而下降,事故频繁,动力设备发展缓慢。原来的先行变为薄弱环节,也是做梦想不到的。 损失的原因,大致为:①“文革”中及所遗留的工程管理上的问题,②物价、地价和设
Over the past 30 years, the railway project has changed greatly. In the 1950s, in a few short years, the nationally divided lines became one and the new lines went straight to Xi’er. Soon afterwards, the southwestern mountainous areas were also built into the initial skeleton of the road network. These great achievements were unimaginable even before liberation. However, since the 1960s, the cost and construction period have increased by several times. Construction machinery has been continuously increased, productivity has been declining, accidents have been frequent, and the development of power equipment has been slow. The original first become a weak link, but also do not dream of. The reasons for the loss are broadly as follows: (1) Problems in the “Cultural Revolution” and the project management left behind; (2) Price, land price and construction
