公路岩溶隧道工程中的地质勘察研究

Research on Geological Exploration in Highway Karst Tunnel Engineering

在路政工程中,隧道建设备受人们关注。为此,文章以某高速公路隧道为例,采用示踪实验的方法,勘察隧址区分布的落水洞与周边暗河出口的连通性,分析地下暗河的展布情况及地下含水介质特征,为地下分水岭位置的确定、岩溶地下水系统边界的划分、隧道涌水量的估算及突泥涌水风险的评价提供了重要依据。研究成果表明,示踪实验的方法在岩溶区的水文地质勘察中具有较高的应用价值。

In road engineering,tunnel construction has attracted much attention.For this purpose,the article takes a certain highway tunnel as an example and uses the method of tracing experiments to investigate the connectivity between the sinkholes distributed in the tunnel site area and the surrounding underground river outlets.It analyzes the distribution of underground underground rivers and the characteristics of underground water containing media,providing important basis for determining the location of underground watersheds,dividing the boundaries of karst groundwater systems,estimating tunnel water inflow,and evaluating the risk of mud and water inrush.The research results indicate that the tracer experiment method has high application value in hydrogeological exploration in karst areas.
