　　The numerical solution to coupled poromechanics is still a challenging task because of several issues:(1)pore pressure instability,(2)large number of unknowns,and(3)ill-conditioning of the discretized system.The use of Mixed Finite Elements can alleviate the numerical oscillations in the pressure solution,but give rise to very large and ill-conditioned systems of algebraic equations.
