unpublished
By using the borehole elastic modulus test and sound wave inspection for typical representative spots of a dam foundation, the deformation behavior parameters of grouted weak rock of workplace foundation are obtained, and the potential relationship between wave velocity VP and elastic modulus E is derived. Then the quality of the rock is evaluated by the wave velocity. Comparative analysis shows that the consolidation grouting is better for the rock with poor engineering property under the
