     in this paper the proper solution to modify circular analysis method of soil-support interaction model for considering the effect of earthquake scattering wave on rock was evaluated. while the tunnel is excavated displacement in rock around the tunnel will be produced which can create stress distribution. interaction diagram is a good approach to understanding the mechanical behavior of tunnel problems. in this field calculation and drawing ground response curve is necessary for specified rock mass, local stress and tunnel geometry. in some numerical methods, more complicated geometry case and different local stress have used. however in all cases, it is necessary important assumption should be accept about the stress-strain behavior, strength criteria and rock failure mechanism. the proper method for allocating the plastic and elastic-plastic domain is circular. in this method, problems are solved by boundary element techniques for diagnosis plastic, elastic-plastic and elastic annulus. case studies have shown that with consider earthquake scattering waves; calculated plastic region may be increase by 1.5 to 4 times. therefore the proper solution method for results modifications was presented.
