东海道新干线开业已经十五年了,目前,东北新干线也已经开始运营。但这两条线路存在着一个共同的特征:即它们都通过或濒临地震多发地带。倘若发生强烈地震,可以预见,该地区的铁路将会遭受诸如路基下沉、桥梁塌落、线路弯曲等设施破坏的灾害。特别是象新干线那样高速,大运量的线路,倘一旦发生列车脱轨、颠覆事故,所招致的巨大危害和深刻影响是极其可怕的。且不说路基下沉这样的原发性线路设备受害情况,为了保证运输安全,必须防止引起继发性的列车脱轨、颠覆等事故。为此,当地震发生后需要尽可能迅速地对列 Tokaido Shinkansen has been in operation for fifteen years. At present, the Northeast Shinkansen has also started operations. However, there is a common characteristic between these two routes: that they all pass or are near the earthquake zone. In the event of a strong earthquake, it is foreseeable that the railways in the area will suffer disasters such as the subsidence of the subgrade, the collapse of bridges, the bending of the lines and other facilities. In particular, the high-speed and high-speed lines such as the Shinkansen line are extremely frightening if the derailments or subversion of trains occur. Not to mention the sinking of such primary road equipment such as the case of road damage, in order to ensure the safety of transport, must prevent secondary train derailment, subversion and other accidents. For this reason, the columns need to be aligned as rapidly as possible after the earthquake
