摘　　要：泥质页岩膨胀是一个象道路、边坡和地下结构等许多领域里的重要问题。水和溶质的流动和泥质页岩的膨胀是受平衡方程、达西定律及质量守衡方程所控制 ,它们是耦合的和复杂的。考虑一个轴对称流动的特殊问题中 ,方程被解耦 ,并使用差分法求解特殊边界条件下 ,解耦后的方程。最后得到孔隙压力 ,溶质浓度和应力在井孔周围的分布。其结果可以应用到分析井孔和巷道的稳定性。The swelling of clay shale is an important problem in many fields, such as road, slope and underground structure. The flow of water and contaminant and swelling in clay shale are governed by the equilibrim equation, Darcy law, mass balance equation, which are coupled and complex. A problem of axisymmetric flow in clay shale is considered, and a Finite Difference Method is used to solve the basic equations under special boundary condition. The distribution of pore pressure, solute concentration and stresses around borehole are obtained. The results may be applied to analyze the stability of borehole or tunnel.
