摘要：

示踪试验作为重要的水文地质试验，长久以来以探明地下水的水力联系、测定地下水流速为主要目标。针对岩溶地区地下水流速较快的特点，提出了一套基于对流稀释作用的数学模型，利用电导率与溶质浓度的正相关关系，可方便准确地计算示踪试验投源井的天然径流量和地下水中示踪剂的背景浓度。根据后寨地下河流域陈旗典型试验区的计算成果，投源井的天然径流量为0.241 4 m³/min，辅以必要的水文地质调查，即可估算地下水流速以及含水层的渗透系数。

关键词: 示踪试验, 天然径流量, 对流稀释, 水文地质参数

Abstract:

Tracer test as an important hydrogeology test, are widely used to explore the hydraulic connectivity underground, measure the groundwater flow velocity. According to the fast flow in karst aquifer, a mathematic model based on the dilution function of convection is proposed. By means of this model and the linear relationship between electricity conductivity and solution concentration, the authors can easily and accurately calculate the groundwater runoff of source well and the tracer concentration in the original groundwater. In this case study, the runoff of source well which in Chenqi of Houzhai underground river basin is 0.241 2 m³/min. Furthermore, supplemented with necessary hydrogeology investigation, the groundwater flow velocity and aquifer conductivity can be estimated.

Key words: tracer test, groundwater runoff, convection dilution, hydrogeological parameters
