西南地区某铁路隧道涌突水地质分析与施工措施

Geological Analysis of Water Gushing and Construction Measures of a Railway Tunnel in Southwestern China

隧道涌水是铁路施工过程中一种十分常见的地质灾害问题,它对隧道施工进度及隧道施工安全具有直接的影响。针对西南地区某铁路隧道施工期间发生的涌突水事故,结合隧道工程地质及水文地质特征,分析了此次涌突水事故的机理,对隧道继续掘进的涌突水风险进行了预测,同时对后续的施工提出了相应措施,确保隧道的安全掘进。

The tunnel water gushing is a very common geological disaster in the process of the railway construction,which has a direct effect on the tunnel construction schedule andsafety. Aiming at the water gushing happened during the construction of a railway in southwestern China,combined with the geological and hydrogeological characteristics,this paper has analyzed the mechanism of water gushing accident,predicted the risk of water gushing for further excavation of tunnel and put forward corresponding measures for subsequent construction so as to ensure safe excavation of tunnel.
