- Abstract
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 natural condition, but for the rock with good mechanics strength characteristic, the improved effort is not very good. However, two test indicators are all satisfied with the analytical requirement. Therefore, this method is effective for grouting quality detection of rock.
