In porous medium, matrix and fluids bear forces together. For analyzing strength and deformation in porous medium, matrix stresses must be calculated. After Terzaghi advanced matrix stress for saturated soil in 1925, many people have used matrix stress in their researches. It is found that there is mistake in Terzaghi's equation. A new matrix stress equation is established.
