dc.description.abstract | In order to investigate the effect of stress history on in-situ test results in granular sediments, a series of CPTs and DMTs are performed on Busan sand prepared in the calibration chamber. K-D is found to be the most sensitive to the stress history among CPT and DMT measurements. E-D and q(c) are observed to be similarly affected by the stress history and, therefore, the E-D-q(c) relation appears to be almost independent of the stress history. The K-D-D-R relation established without considering the stress history is likely to overestimate the relative density of OC sand. It is shown that the existence of the pre-stress of the granular sediment can be indirectly recognized by an estimation of the relative density larger than 100% when using the K-D-sigma(v)'-D-R relation suggested for NC sand. Although q(c)/sigma(v)'-K-D/K-0 and E-D/sigma(v)'-K-D/K-0 relations are heavily influenced by the stress history, q(c)/sigma(m)'-K-D/K-0 and E-D/sigma(m)'-K-D/K-0 relations are observed to be independent of the stress history. Based on these relations, charts to evaluate the K-0 value from q(c) and/or DMT indices are developed for both NC and OC sands. The design chart based on E-D/sigma(m)'-K-D/K-0 and E-D/sigma(v)'-K-D/K-0 relations is expected to be practically useful as the usage of this chart requires only DMT indices. The developed design charts are applicable to Busan sand but different sets of equations and charts may be developed for other sands. (C) 2010 Elsevier B.V. All rights reserved. | - |
