摘要
由于日益紧张的地下空间和需要考虑降低工程造价等原因,城市连拱地下工程大量涌现,而城市地下多连拱工程具有埋深浅、大跨度、非对称和中(边)墙形式多样等特点。由于结构形式在地铁运营安全中发挥重要的作用,因此对城市连拱地下结构的抗震性能应具有全面的认识。基于对大量城市连拱地下工程案例的归纳整理,文章将城市地下连拱结构分为单拱截面、双连拱截面、三连拱截面和四连拱及多连拱截面地下结构,在总结已有大量城市连拱地下工程特点的基础上,分别阐述各类连拱截面地震响应研究现状和进展,指出现有研究中存在的问题,并对今后尚需进一步研究的方向给出了一些抛砖引玉的建议。
Due to the increasingly tight underground space and the requirements for reducing engineering costs,urban underground multi arch projects have emerged in large numbers.The urban underground multi-arch structure has the characteristics of shallow depth,large span,asymmetry and various forms of medium(edge)walls.As the urban underground multi-arch structure plays an important role in the safety of subway operation,so it needs to have a comprehensive understanding the seismic performance of urban arched underground structures.Based on the summary of a large number of urban arched underground engineering cases,the urban multi-arch underground structures are divided into single arch section,double arch section,three-arch section,four-arch and multi-arch section.In this paper,on the basis of summarizing the characteristics of a large number of urban arched underground engineering,the research status and progress of seismic response of each arch section system are elaborated separately.The paper points out the shortcomings and existing problems in the existing researches,and gives some suggestions on the direction of further research in the future.
