岩土体渗透性参数是评价地下水资源,研究地下水运动规律的重要水文地质参数。微水试验相较于传统的测试方法是一种现场快速测定岩土体渗透性参数的方法,其试验时间短,对地下水及周边环境影响甚微,具有广泛的应用前景。该文采用两种微水试验的Kipp(1985)模型和Cooper(1967)模型对现场试验结果进行了计算分析,并将计算结果与传统抽水试验成果进行对比分析,两种试验成果拟合较好,表明微水试验测试方法可用于测定介质的渗透系数。
The permeability parameters of rock and soil are important hydrogeological parameters for evaluating groundwater resources and studying the law of groundwater movement. Compared with the traditional test method, the micro-water test is a rapid on-site determination of permeability parameters of rock and soil, its test time is short, it has little influence on groundwater and the surrounding environment, and has a wide range of applications. In this paper, the Kipp (1985) model and the Cooper (1967) model of two kinds of micro-water tests are used to calculate and analyze the field test results. The results are compared with the results of traditional pumping tests. The two test results fit well , Indicating that the micro-water test method can be used to determine the permeability of the medium.
