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。

Abstract

Research purposes：A large water bursting happened at the entrance of the tunnel to bring a lot of disasters. The hydro-geological data and in-site observed data were analysed to find out the reasons for the water bursting and sum up the laws of the appearance of water bursting for the purposes of making the remediation schemes for design and construction of the tunnel and avoiding the construction risk.

Research conclusions：The topography junction and lithology interface between mountain watershed consisting of Silurian clastic limestone and mountain slopes consisting of Qixia and Maokou groups limestone were the catchments. The 3# underground river developed in P1q+m stratum where was rich of water with three different types of water-filled layers. They were related to 3# underground river in various degrees. Water inrush brought the water of the underground river into the tunnel. The rechanneled underground river remained the characteristics of 3# underground river, such as pipeline flow, dynamic changes of runoff quantity and precipitation-runoff relations etc. The diversion of the underground river would have a certion impact on the environment, and the silt and stones brought by the water inrush would cause some difficulties in construction, operation and maintenance of the tunnel.
