地下水非稳定流理论在饱和土渗透固结中的应用

Application of Groundwater Non-stable Liquid Theory in Infiltration Concretion of Saturated Soil

计算饱和土层的渗透固结变形,通常采用太沙基的一维固结理论,在条件相同的情况下,利用承压水渗透理论同样能建立饱和土层一维渗透固结微分方程,并使用有限差分法求解该微分方程,结果表明,其结果与太沙基的一维固结理论是一致的;将地下水非稳定流理论应用于饱和土层的渗透固结变形中可以方便地使用目前较为成熟的Modflow软件求解。

Terzaghi＇ s consolidation theory of one dimension is usually adopted to calculate infiltration concretion deformation in saturated soil. Under the same situation, using confined water saturated theory also can establish a infiltration concretion differential equation of one dimension in saturated soil. By using finite difference method, this differential equation can be calculated. The result is coherent with TetT^aghi＇ s consoli- dation theory of one dimension; ff underground water non-stable theory is applied in infiltration concretion deformation in saturated soil, the widespread software Modflow can be conveniently adopted to get solution.
