Comparative Study on Laboratory and Field Test of Maximum Dynamic Shear Modulus

Abstract:

The dynamic shear modulus (DSM) is the most basic soil parameter in earthquake or other dynamic loading conditions and can be obtained through testing in the laboratory and in the field. The experimental result of maximum DSM by using resonant column devices is compared with the field test data obtained from shear wave velocity measurement in the paper. By testing two engineering sites, the reason of difference of the maximum DSM between laboratory and field test is presented and the effect of the consolidation ratio on the maximum DSM is investigated. The results here indicate that consolidation ratio is one of the most important influence factors to make a great difference of the maximum DSM between laboratory and field test. By comparing to the isotropic consolidation, the consideration for the actual anisotropic consolidation makes the maximum DSM increase up to the value obtained by field test, and the error decreases significantly.
