地震及列车振动荷载下的地铁震害特点及防治

Earthquake and Damage under Train Vibration Load in Subway

地震及地铁列车振动荷载在一定情况下会对地铁造成破坏甚至使其功能丧失,产生严重的后果。因此,必须对地铁的抗震研究予以足够的重视。介绍了近年来这方面的研究成果,包括在地震及列车振动荷载作用下地铁车站、区间隧道及地铁地基破坏的形式、特点及防治措施。

Subway can be damaged and lose its functions during earthquake and tremendous vibration of metro trains. A study of anti-seismic structure in the subway is necessary. In this paper, the author introduces the recent research achievements, including the patterns and characters of damage in subway stations, subway section tunnels and subsoil under earthquake or the train vibration load, discusses some preventive measurements.
