我国铁路运量增长速度很快,急需发展铁路重载运输。轨道是铁路运输的基本工程,在列车运行时起承载和导向作用。然而,我国铁路现行轨道设备的技术水准较低,轨道结构的承载能力太弱,直接影响了线路的通过能力,而且严重的妨碍我国铁路重载运输的发展。因此,迫切需要开展“60型重型轨道结构成套技术” The rapid growth of rail transport in our country urgently needs the development of railroad heavy haul transportation. The track is the basic project of railway transportation, which plays a leading and guiding role in the train operation. However, the current railway equipment in our country has a relatively low technical standard and the bearing capacity of the track structure is too weak, which directly affects the passage capacity of the railway and seriously hinders the development of heavy rail transportation in our country. Therefore, there is an urgent need to carry out the “60-type heavy-rail structure technology package”
