Abstract Research purposes: The vertical wave velocity and compressive strength of the rock ( rock mass) are the very important indexes for appraising the rock mass strength，the slope stability and surrounding rock classification．In this paper，based on the tests data，the statistics is made for the average values of the vertical wave velocity and compressive strength of the rocks of all kinds of stratum，the macroscopic relation between the vertical wave velocity and compressive strength of the rocks is analyzed，and the model is established for the macrocopic quantitative relation between them． All these are crucial to appraising the rock mass quality，classification of the surrounding rock of tunnel，saving the test cost，shortening project construction time and checking the reliability of the test result．

Research conclusions: ( 1) When the rock ( rock mass) is dense，hardy，complete and fresh，its vertical wave velocity is big，otherwise its vertical wave velocity is low when the rock ( rock mass) is weak，serious weathering，watery and dissected． ( 2) The vertical wave velocity of the rock is directly proportional to the cube root of rock compressive strength，and the vertical wave velocity of the rock mass is directly proportional to the cube root of the compressive strength of rock mass and the square root of the integrity index of rock mass． ( 3) The practices show the model for the macroscopic quantitative relation between the vertical wave velocity and compressive strength of rock( rock mass) is reliable．

Key words： rock ( rock mass) vertical wave velocity compressive strength quantitative relation
