Abstract
Based on theory analysis,the deformation formation of surrounding rock in round tunnel was founded and the influence of rock characteristic on surrounding rock deformation was analyzed.The results were drawn that the velocity of different kinds of rock deformation is different,deformation of soft rock is very obvious in deep tunnel.the increasment of cohesion and fraction angle by injecting serosity is main method to control deformation of surrounding rock.
