摘　　要：地铁超深基坑工程作为超危大工程,其施工具有土方量大、基坑深、施工风险高、未知因素多、工艺及支护标准要求高等特点,因此开展超深地铁基坑支护施工技术研究,对推动我国基坑支护技术发展具有重要意义。本文通过对北方某市中心地铁超深基坑支护结构研究,探索支护桩+锚索支护结构在超深基坑应用中的可行性,为同类型工程施工提供方案借鉴。As an ultra-dangerous project,the construction of ultra-deep subway foundation pit engineering has the characteristics of large amount of earthwork,deep foundation pit,high construction risk,many unknown factors,and high requirements for process and support standards,so it is of great significance to carry out research on ultra-deep subway foundation pit support construction technology to promote the development of foundation pit support technology in China.This paper explores the feasibility of the support pile+anchor cable support structure in the application of ultra-deep foundation pit through the study of the ultra-deep foundation pit support structure of a subway in a city center in the north,and provides a scheme reference for the construction of the same type of project.
