考虑含水层参数随应力变化的地下水渗流

Groundwater Seepage at the Variation of Aquifer Parameter with Stress

含水层参数的研究是地下水动力学和土力学中的一个重要课题．文中在室内模型试验的基础上，通过大量的分析和计算，得出因抽水引起的土骨架压密的应力－应交关系，含水层的渗透系数与有效应力增量的相关关系．同时采用所提出的经验关系式椎导了变参数地下水非稳定渗流数学模型．

The study of the aquifer parameter is a major problem in groundwater dynamics and soil mechanics. On the basis of laboratory model tests, and by analyzing and calculating a large number of experimental data, the stress-strain relationship is obtained for the compaction of the soil skeleton due to pumping,and the functional relationship between the coefficient of permeability and effective stress increment is obtained in this paper. The mathematical model for the variable parameter on the groundwater unsteady now is derived by using the empirical formula proposed in this paper.
