Abstract | In design of large-scale earth structures such as hydraulic-placed fills for artificial islands or tailings dams, a major
concern is the susceptibility of the silty sands involved to flow failure or liquefaction. Compared with uniform clean sands that have
been extensively studied in the laboratory, the large-strain behavior and liquefaction potential of silty sands is not yet well understood
partly due to the complex role of the fine particles. A difficult problem in the liquefaction evaluation in practice is to evaluate the insitu
state of the soil; this is because for sandy soils it is extremely difficult and costly to obtain high-quality undisturbed samples. This
paper presents a framework for evaluation of the in-situ state of silty sands by using shear wave velocity measurements. The
framework is built upon a comprehensive experimental program involving shear wave measurements for both clean sand and sandfines
mixtures in conjunction with interpretation and analysis in the theory of critical state soil mechanics. Since shear wave velocity
can now be reliably measured both in the laboratory and in the field and since the initial state controls different aspects of the stressstrain
behavior of sandy soils, the proposed framework is highly promising in a variety of geotechnical applications |
