一、概况建国以来,我国铁路建设事业蓬勃发展,新线大量延伸,初步形成了一定规模的铁路网。与此同时,不少既有干线进行了技术改造,以提高通过能力满足日益增长的运输需要。通过大规模铁路建设,有力地促进了国民经济的腾飞,成绩是巨大的。然而,由于一些新线运量不落实建成后往往未能达到预期效果。虚糜运能,浪费投资。相反地,沿海主要干线的运量虽然不断地上升,却未得以及时扩建加强,致运量与运能矛盾十分尖锐。
I. Overview Since the founding of the People’s Republic of China, the cause of railway construction in our country has been booming. A large number of new lines have been extended and a certain scale of railway network has been initially formed. In the meantime, many of the existing trunk lines have undergone technological transformation to improve their capacity to meet the growing transport needs. Through the large-scale railway construction, which has effectively promoted the rapid development of the national economy, the achievements have been enormous. However, due to the lack of implementation of some new routes, they often fail to achieve the expected results. Ximian Yun, a waste of investment. On the contrary, although the traffic volume of major trunk lines along the coast has been rising steadily, it has not been expanded and strengthened in time, causing a sharp contradiction between the volume of transport and the capacity of transportation.
