渗透系数空间变异性研究

Study on the spatial variability of hydraulic conductivity

  • 摘要: 水文地质参数的空间变异性是随机理论研究的基础,而渗透系数是最为重要的水文地质参数。国外有关渗透参数空间变异性的研究工作已开展很多,但渗透系数究竟服从什么分布目前尚无确切答案。利用Borden含水层试验数据,对渗透系数的空间变异性进行探讨,结果表明若处理方法得当,渗透系数应服从对数正态分布。同时,还对今后野外开展含水层渗透系数空间变异性试验研究提出几点建议。

     

    Abstract: The spatial variability of hydraulic properties is the basis of stochastic research on groundwater.The hydraulic conductivity is the most important parameter.There is still no exact answer to the question about the distribution of hydraulic conductivity though studies dealing with this topic are numerous.In this paper,a discussion of Sudicky's (1986) field experiment for the geostatistical characterization of the hydraulic conductivity at the Borden aquifer in Ontario,Canada is performed by using the different schemes of the data disposal.The results of the analysis suggest that the distribution of hydraulic conductivity is lognormal by using the appropriate method.In addition,some useful advices are provided for carrying out the field study on the spatial variability of hydraulic conductivity in the future.
