摘　　要：本文介绍了大瑶山隧道利用含盐示踪剂对地下水进行连通试验;利用天然同位素分析和水化学分析对地表水及地下水进行了连通试验,查明了连通关系、补给来源和范围,为隧道岩溶水害整治提供了科学依据。In order to treat karst water-in-flow in a long and large tunnel, the source and supply of karst water should be found out first. In other words, the feeding source and range of karst water must be ascertained. The connecting experimental study on karst ground-water in flow of tunnel is a more efficient method to solve these problems.A case about the connecting test on karst pouring water of Dayaoshan Tunnel is introduced in this paper. The two following methods have been used to find out the relation between surface water and groundwater in tunnel. One is to use salt as tracer, i. e. , putting salt in the cave on the ground and receiving in tunnel. The other is to utilize the analysis of enviormental isotopes and hydrochemical contents. By experiment, the feeding source and range of karst - in - flow in tunnel have been found out. On the basis of the results, the karst water-in-flow in Dayaosan Tunnel can be treated.
