摘要: 应用有限差分法,对弹性孔隙介质在无水平应力作用情况下的充水过程和充水稳定后部分区域阻塞情况下水头调整过程进行了分析。研究结果显示:就含水层内某一点而言,其水头除与位置和含水层的边界条件有关外,还与它本身及其周围区域的压力传导系数有关;含水层不同程度的阻塞会引起给定点的水位变化,而且不同的阻塞范围对含水层的水头分布和给定点的水头变化有很大的影响。

Abstract: The processes of filling water into elastic porous medium without the action of horizontal stress and water head adjusting caused by incomplete block in partial region after fulling water were analyzed by using the method of finite difference.It is found that for a certain point in aquifer the water level is not only related to the position of the point and the boundary conditions of the aquifer,but also associated with the pressure conductivity of itself and surrounding areas.The block at different degree in aquifer may cause the change of water level at a given point.And the size of block region can greatly affect on the distribution of water level in aquifer and the change of water head.

Key words: Permeation flow, Porous medium, Numeral simulation
