Abstract In order to reduce the dependence of GSI system on the field geological observation，to reduce the difficulty of its application and to reflect more accurately the characterization of rock mass from the surface to a certain depth，a new GSI system in terms of the longitudinal wave velocity was built based on the correspondence of intactness and weathering between the results existing research and GSI systems. The geological strength indexes of rock mass from the region of Dagangshan dam were obtained from the new system. Its feasibility was confirmed through the analysis of the distributions and correlation between the results obtained from the new GSI system and empirical formula，and between the predicted deformation modulus of rock with GSI and the measured one. The squared ratio of the weathered rock to unweathered rock is a reasonable input parameter which represents the weathering degree. The input parameters of GSI system can be replaced with the intactness index and weathering index of rock.

Key words： rock mechanics geological strength index(GSI) longitudinal wave velocity blocky rock mass intactness index of rock mass weathering index of rock
