摘要
以某地铁工程为例,介绍了暗挖隧道的主要设计参数,并从竖井、大管棚、洞门施工、分部进洞开挖、初期支护、施工注意事项等方面对暗挖施工技术进行了分析、研究与总结,积累了城市浅埋暗挖隧道CRD工法的施工经验。
Taking the subway project as an example,this paper introduces the main design parameters of the darkly excavated tunnel firstly.Then this paper analyzes,studies and summarizes the excavation construction technology from the following aspects: shaft,large pipe shed,door construction,divisional excavation,initial support,construction precautions and so on. The experience has been accumulated for the CRD method of shallow buried tunnel in the city.
