摘要：
A generalized continuum theory for porous media is formulated by allowing for thepossibility of microrotation. The basic balance laws are presented and based on thermodynam-ical consideration a set of constitutive equations are derived. The theory naturally givesrise to the generation of antisymmetric stress tensor and existence of couple stresses. Thebasic equations of motion are derived and discussed.The problem of coupled shear, dilata-tional, porosity and microrotational wave propagation is investigated and the dispersion rela-tion for various waves are derived and discussed.
