摘要
宁会隧道在穿越复杂山区突遇涌水。经过分析涌水量监测数据,并综合运用物探、钻探等探测方法,明确了岩溶形态和位置,证实了降水对洞内涌水的补给。为减少涌水突泥事故不利影响,提出了迂回左线施工的后期施工方案,提高了右洞停工时的隧道施工进度。
Ninghui Tunnelen countered water in rush through complex mountainous areas.Through the analysis of water in flow monitoring data,and the integrated use of geophysical exploration,drilling detection methods,the karst morphology and location are clarified,and the recharge of precipitation to water inrush in the tunnel is confirmed.In order to reduce the adverse effects of water inrushing,the late construction scheme of circuitous left line construction is proposed,which improves the construction progress of the right tunnel when the right tunnel is shut down.
