【摘要】：正地铁隧道作为生命线工程的重要组成部分,其抗震问题日益受到关注。早期人们认为地下结构受周围土体的约束,具有良好的抗震性能,但1995年日本阪神地震造成了神户市部分地铁车站和区间隧道受损严重,震后修复困难,产生巨大的经济损失,才使人们意识到地下结构的抗震问题也不容忽视。我国是世界上多地震国家之一,处于活动期的断层在我国分布较广,为避免使结构遭受活断层错动引发的震害,避让措施成为地铁隧道建设选线设计中的
[Abstract]:As an important part of lifeline engineering, the seismic problem of metro tunnel is paid more and more attention. In the early days, it was believed that underground structures were constrained by surrounding soil and had good seismic performance. However, the Kobe earthquake in Japan in 1995 caused serious damage to some subway stations and interval tunnels in Kobe City, resulting in difficult repair after the earthquake, resulting in huge economic losses. Only when people realize that the seismic problem of underground structure can not be ignored. China is one of the countries with many earthquakes in the world, and the faults in active period are widely distributed in our country. In order to avoid the earthquake damage caused by the active fault dislocation, the avoiding measures have been used in the route selection design of subway tunnel construction.
