青云山隧道出口左线局部涌水突泥处理方案研究

Study on Treatment Project of Gushing Burst on the Left Line of Qingyunshan Tunnel Exit

青云山隧道是具有多种不良地质的特长深埋公路隧道,出口段施工过程中遇到断层发生了涌水、突泥灾害,造成了坍塌事故。通过对灾害产生的原因及坍塌进行分析研究采取了一系列行之有效的处理措施,快速的完成了突泥及坍塌段的施工。

Qingyunshan tunnel is a deep buried highway tunnel with many kinds of unfavorable geological features. During the construction of the exit section, there was a gushing disaster and a muddy outage resulting in a collapse accident. Through a series of effective measures to analyze the causes and collapses caused by the disasters, the construction of mud slips and collapsed sections has been completed rapidly.
