%X 贵州德江隧道工区内岩溶水文地质条件复杂、岩溶强烈发育,在不到4 km的范围内发育了两条大中型地下河(闹水岩地下河和池坝地下河),隧道岩溶问题突出,亟需开展德江隧道区地下河研究,以确保隧道施工安全及全线顺利贯通。本文为了摸清闹水岩地下河系统北侧汪家坝、黄泥溪一带与闹水岩地下河的水力联系,同时确定系统北部边界及地下水系统结构特征,进行了示踪实验。研究确定了地下河系统的边界和部分水流流速,并结合水文地质调查资料,进一步分析了地下水系统特征。对示踪试验在研究地下水系统问题中的应用问题进行有益探索,指导了工程实践。
The karst hydrogeological conditions in Dejiang tunnel area in Guizhou are complex and karst is strongly developed. Two large and medium-sized underground rivers (Naoshuiyan underground river and Chiba underground river) are developed within less than 4 km. The tunnel karst problem is prominent. It is urgent to carry out the research on the underground river in Dejiang tunnel area, so as to ensure the safety of tunnel construction and the smooth connection of the whole line. In order to find out the hydraulic connection between Wangjiaba and Huangnixi in the north of Naoshuiyan underground river system and the Naoshuiyan underground river, and determine the northern boundary of the system and the structural characteristics of groundwater system, a series of tracer experiments were carried out. In this study, the boundary and partial flow velocity of groundwater system are determined, and the characteristics of groundwater system are further analyzed combined with hydrogeological survey data. This paper makes a beneficial exploration on the application of tracer test in the study of groundwater system, which guides the engineering practice.
