地铁车站穿越地下大空间及地铁隧道安全分析

Safety analysis on metro station crossing large underground space and metro tunnel

随着我国城市土地资源的日益紧缺,地下空间的开发利用越来越受到重视。但地下空间的大量开发又会导致他们之间相互影响和制约。以某市地铁车站穿越地下大空间及既有地铁隧道为例,采用数值分析的方法,对其安全性进行了研究,为工程设计提供参考。

The development and utilization of underground space are attaching more and more attention as the land resource is increasingly scarce in Chinese cities. But, there has an interaction effect between different underground spaces by the large scale development of underground space. Taking tunnels crossing large underground space and existing metro station for example, the safety of underground space and existing station was studied in this paper by numerical simulating, so as to provide an important basis for the metro designing.
