地铁结构地震破坏及处理措施
|
摘要
地铁工程抗震问题已成为城市工程抗震和防灾减灾研究的重要组成部分,虽然我国在该领域做了大量工作,也取得了丰富的成果,但迄今为止还没有独立的地铁结构抗震设计规范。文章论述和分析了"5.12"汶川地震对成都地铁1号线一期土建工程结构的破坏情况和工程处理措施,提出了对地铁结构抗震设计关键技术的一些认识,可为国内外地铁工程抗震设计提供参考。
Aseismic issue of metro engineering has become an important component of aseismic and disasterprevention and disaster-reduction research in urban engineering.Though in China a lot of work has been done in this field with abundant achievements,so far there is not an independent code on aseismic design of metro structures.Some understandings on key technologies for aseismic design of metro structures have been obtained through the detailed description and analysis on damages of civil engineering structures of Chengdu metro Line 1 Phase 1 in the "5.12" Wenchuan Great Earthquake and corresponding engineering treatment measures.This paper may provide due guidance on aseismic design of metro engineering at home and abroad.
