摘要:

为探讨岩溶隧道施工涌水对地表水文环境的影响程度及范围,以圆梁山深埋特长隧道工程施工为依托,对隧道地表水文进行监测和分析。主要研究内容及结论为: 1)介绍圆梁山隧道向斜段地表水文地质情况,说明进行悬挂泉流量及地表井泉水位监测可以评估隧道突涌水对地表环境的影响程度及范围; 2)进行地表大气降雨及隧道涌水量观测并对比,可以据此判定隧道与地表的水力连通性; 3)证明隧道施工会对隧道洞身上方泉眼产生影响,但对山顶植被影响较轻; 4)在岩溶隧道施工中进行地表水文监测是必要的,对施工具有指导作用。

Abstract:

The ground surface hydrology of Yuanliangshan deepburied extralong tunnel is monitored and analyzed, so as to obtain the degree and range of the influence on the ground surface hydrology imposed by water burst occurring during the construction of karst tunnels. Conclusions drawn are as follows: 1) The degree and range of the influence of water bursts on the ground surface hydrology can be evaluated by means of monitoring the flow volume of hanging springs and the water levels of ground surface well springs. 2) The hydraulic conductivity between the tunnel and the ground surface can be deduced from monitoring of and comparison and contrast between ground surface rainfalls and water bursts. 3) The tunnel construction has some influence on the springs above the tunnel, but has little influence on the vegetations. 4) It is necessary to monitor the ground surface hydrology, which can provide reference for the construction of karst tunnels. 
