Abstract Based on the detection data of more than twenty large-scale hydropower projects，the wave velocity changes before and after consolidation grouting of rock masses under different conditions of fault fracture zone， weathered zone，and excavation effecting zone are analyzed；and the relationship between the increasing rate of wave velocity after grouting and the wave velocity before grouting is established. Moreover，the relationship between change of wave velocity and deformation parameters of rock mass is discussed. And the comparison between detection data and test results of consolidation grouting for foundation of intake tower in Pubugou hydropower station is carried out. The results show that：(1) The groutability of rock mass is the decisive factor of consolidation grouting effect.(2) Different rock masses have their corresponding fixed ranges of increasing rate of wave velocity. Under confidence interval of 95%，the ranges of increasing rate of wave velocity of fault fracture zone，weathered zone and excavation effecting zone are 14%–38%，10%–25% and 6%–16%，respectively. (3) The relationship between increasing rate of wave velocity and wave velocity before grouting can be used to predict the effect of consolidation grouting.

Key words： hydraulic engineering dam foundation consolidation grouting increasing rate of wave velocity groutability
