- Abstract
- The aim of this experimental study is to estimate the maximum shear modulus (G(max)) of normally consolidated clayey soils using the results of a dilatometer test (DMT). A series of DMTs was conducted at the Busan New Port and Noksan sites in South Korea. In addition, basic index tests, bender element tests (i.e., shear wave velocity (V-s) measurements), and standard 1-D consolidation tests were performed using the undisturbed specimens. The results demonstrate that the G(max) of normally consolidated Busan clays cannot be adequately captured by the horizontal stress index (K-D)-based empirical formula. Therefore, a G(max) estimating formula for normally consolidated clayey soils is newly suggested in this study using the dilatometer constrained modulus (M-DMT) and stress-normalized material index (I-D). Most notably, the estimated G(max) values using the suggested formula are comparable with the measured G(max) of both this study and the previous study on normally consolidated clayey soils.
