| Abstract: |
| Piezoceramic bender elements technology was firstly used to test the dynamic shear modulus of polymer grouting materials. The test project and related moulds were made for it. The impulse frequency of piezoceramic bender elements was determined for testing polymer grouting materials. Based on it, the influence on polymer dynamic shear modulus of its density and impulse frequency was analyzed, the dynamic shear modulus and static elastic modulus were contrasted and the relation of polymer grouting materials and the materials of earth dam was studied. The experimental research provided theoretical basis and reference for its dynamic response analysis and engineering application of polymer grouting materials. |
