In this paper, some opinions in the mechanical model for saturated soils with isolated pores are discussed. Based on the Carroll's mechanical response theory of fluid-saturated porous materials, the stress-strain relations and bulk modulus for this kind of soils are derived again. As a result, for the bulk modulus of quasi-statistic wave, the condition of isolated pores on soils has same effect with no relative movement between solid and fluid, zero permeability or infinite fluid viscosity, and there is no difference whether the pore is isolated or not. The bulk modulus derived here is the same as that in Blot's theory.
