影响高铁隧道施工安全因素分析及相应措施探讨

The safety influencing factors analysis and corresponding measures on high-speed railway tunnel construction

高铁隧道施工,是影响高铁建设工期的关键工序之一,施工时存在大量的不安全因素。从隧道开挖方式入手,分别从地质岩性、围岩产状及岩层节理发育、地下水等方面,详细分析了隧道开挖时可能出现的各种不安全因素并对其引发的严重后果进行了系统分析,同时,探讨针对这些不安全因素产生的原因应采取的相应措施。

The high-speed rail tunnel construction is one of the key processes of affecting the construction period in high-speed rail construction,and at the same time it still has a large number of unsafe factors.This article begins with a tunnel excavation way,and analyzes in detail all kinds of unsafe factors and the serious consequences caused by the system during the tunnel excavation respectively from the geological lithology,groundwater occurrence of surrounding rock,joint development and the strata,etc..At the same time,the different respondent measures being taken have been discussed according to the causes of these unsafe factors.
