Application of In-situ Sonic Wave Test Method in the effect evaluation of grouting treatment in Weak Rock
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 obtainederived.Thenthequalityoftherockisd, and the potential relationship between wave velocitywavevelocity 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 goodmechanicsstrengthgrouting is better for the rock with poor engineering propecharacteristic,theimprovedeffortisnotrty under the natural condition, but for the rock with good mechanics strength characteristic, the improved effort is not very good. However, two test iTherefore,thismethodiseffectiveforgroutingqualitydetectionofrockndicators are all satisfied with the analytical requirement. Therefore, this method is effective for grouting quality detection of rock.
