本世纪80年代末,在我国5.3万余公里的铁路上,已修建了4800余座、总长度约2250公里的隧道。与此同时,在日本的铁路上则建成了4500余座、总长度约2500公里的隧道。相比之下,我国的铁路隧道在数量上位居各国榜首,而日本的铁路隧道则是在长度上高居首位。
At the end of 1980s, more than 4800 tunnels with a total length of about 2,250 km have been constructed on 53,000 km of railway in our country. In the meantime, more than 4,500 seats and a total length of about 2,500 km of tunnels have been built on Japanese railways. In contrast, the number of railway tunnels in our country tops the list of countries, while the number of Japanese railway tunnels is the highest in length.
