| Abstract: | In this article a discussion is held on the relationship between the modulus of soil deformation and the shear wave velocity with a study performed as well of the moduli of gravel pile deformation. From the analysis of field test data, a regression model is obtained of the moluli of the pile deformation. Based on the formula of soil stress ratio and modulus ratio of the pile, and through establishing the relation Raleigh wave, of which the influential elements are also discussed. By way of engineering instances, a comparison is conducted between the computed value and the static load test value to prove the test reliable. |
| Keywords: | Compound foundation stress ratio shear wave velocity Raleigh wave modulus of deformation |
