Soft rock has the characteristic of time dependency, that is to say, creep and/or strength-reduction. Ground-pressure toward tunnel linear due to plasticity with strength-reduction of rock is expressed using a finite difference method, which is especially proposed by Cundall and is well expressed plastic flow and large-strain. In this paper, the formulation proposed by Sato is adopted as the model of strength-reduction with time dependency of rock and be applied for the evolution of plastic zone. Furthermore, the effects of reinforced tunnel linear are investigated with the different time of construction. The development of the estimation method for appropriate time and reinforced tunnel linear will be expected.
