摘　　要：随着城市地铁建设的密集化,地铁车站出入口位置周边环境也更加复杂。为确保车站出入口施工安全,其中斜坡段多采用俯挖施工,但受地面占地、明挖段及周边复杂环境制约,需根据实际情况及时调整施工方案。本文以北京地铁17号线东大桥B出入口工程为依托,对地铁车站出入口快速施工及风险控制技术进行研究,提出在做好周边施工风险控制的同时,暗挖斜坡段采用仰挖法施工技术,确保了施工工期,加快了施工效率。但仰挖施工技术应用于出入口斜坡段可借鉴的工程经验有限,施工过程中存在一定安全风险,需做好施工控制措施。With the intensification of urban subway construction,the surrounding environment where the entrances and exits of subway station are located has become more complex.In order to ensure the safety of construction at the entrance and exit of the station,the slope section is mostly constructed by downward excavation.However,due to the constraints of ground occupation,open excavation section,and complex surrounding environment,the construction plan needs to be adjusted in a timely manner according to the actual situation.This article is based on the entrance and exit project of the East Bridge B on Beijing Subway Line 17 to study the rapid construction and risk control technology for entrances and exits of the subway station.It is proposed that while controlling the construction risks in the surrounding area,the slope section of the hidden excavation should be constructed using down-top excavation method,which ensures the construction period and speeds up the construction efficiey.However,the engineering experience that can be learned from applying this construction technology to the entrance and exit slope section is limited,and there are certain safety risks during the construction process.Therefore,it is necessary to take effective construction control measures.
