宜万铁路马鹿箐隧道水文地质分析及涌水预警

Hydrogeology Analyses and Water Piping Warning Technology of Malujing Tunnel in Yiwan Railroad

马鹿箐隧道是宜万铁路八座I级风险隧道之一,在DK255+978发育大型高压富水充填溶腔。泄水洞揭穿该溶腔后,多次出现大规模突水突泥。介绍了马鹿箐隧道水文地质背景、水文专项监测、峰值涌水量预测及水文地质预警等相关情况,可为类似工程的水文地质分析和预警提供参考。

Malujing tunnel is one of eight Grade I risk tunnels along Yiwan railroad. Large karst rock cavities were developed with high water pressure at DK255 ＋978. After drainage pipe was drilled through cavities, water and mud inrush happened many times. Researchers introduced hydrogeology background of Malujing tunnel in this paper. Hydrogeology monitoring, estimation of peak water inrush and hydrogeology warning technology were also included.
