摘要： 基于孔隙变化的力学响应方程和尾矿土动态淋溶的实验结果，建立了尾矿沉积土变形的压力-孔隙度-浓度之间的关系，并在此基础上建立了考虑酸溶液作用下尾矿沉积土变形的应力-渗流-化学耦合数学模型。

Abstract: The mathematical deformation model of tailing deposits is established by using the relationships among the stressporosityand fluid concentration. The characteristics of porosity change in the tailing deposits are based on the mechanical performance and the dynamic leaching test results. This coupled model tailing deposit model with the coupling of stressseepagechemical interactions is also consider the effect of acid solutions.

Key words: Acid Solutions, Tailing Deposits, Coupling of Stress--Seepage--Chemical Interactions
