【Abstract】 This paper chiefly describes the forming theory of elastic wave in elastic medium,and analyzes the influencing factors of elastic wave velocity and excavation degree of rock and soil mass.It finds out the common physical property that influences elastic wave velocity and excavation degree of rock and soil mass and gets the conclusion that it is possible to divide excavation degree by the solution of elastic wave velocity of rock mass.更多还原
