基于矿山法的地铁隧道开挖及支护施工技术

Construction Technology of Subway Tunnel Excavation and Support Based on Mining Method

为探究基于矿山法的地铁隧道开挖及支护施工技术,以深圳市某地铁轨道交通为工程背景,在工程概况分析基础上,提出了矿山法总体施工方案,并对该地铁隧道施工过程中的重难点进行梳理和分析,结合地质地形条件和总体施工方案,提出有针对性的应对控制措施,对矿山法隧道开挖以及开挖过程中的支护进行了详细研究。

In order to explore the excavation and support construction technology of subway tunnel based on mining method,the overall construction scheme of mining method is proposed based on the engineering background of a subway rail transit in Shenzhen City and the general analysis of working conditions.The key and difficult points in the construction process of the subway tunnel are sorted out and analyzed,and the geological terrain conditions and overall construction scheme are combined,targeted countermeasures and control measures are put forward,the excavation of mine tunnel and the support in the excavation process are studied in detail.
