| 摘 要： | 研究目的:野三关隧道出口突发性大涌水,造成灾害。研究与分析施工资料、既有水文地质资料及现场观测资料,探究其原因,总结其规律,有效地确定其设计、施工整治方案,规避施工风险。研究结论:志留系碎屑岩组成的山地分水岭与栖霞组、茅口组灰岩组成的山地斜坡之间的地貌交界处和岩性界面处是汇水富集的地方;P1q+m富水地层中发育3#暗河,存在3个不同类型的充水层,它们都与3#暗河有不同程度的联系,隧道突水将暗河导入隧道;改道后的暗河继承、保留了原3#暗河的管道流特征、径流流量动态变化特征、降雨-流量关系特征等;暗河改道将对环境产生一定影响、大流量水流突出的泥石和随带的泥沙对施工和营运养护将造成困难。
