The experimental and analytical study on the detailed estimation of the fracture energy of concrete as a porous permeable material, which is partially saturated with water, was performed. In the analytical estimation, at first, the coupled model with water and concrete solid in which the fracture mechanics was introduced was developed and then the analytical estimation for the fracture energy, which is, defined the effective stress considering the effect of pore water pressure was performed. In the experimental estimation, the effect of pore water pressure on the fracture pattern of concrete was estimated and then the experimental estimation for the fracture energy of concrete in which the pore water pressure occur was performed.
