Abstract
Soil liquefaction is a major interest with regard to the engineering performance of structures and facilities located in regions of seismic risk. While significant advances have been made in the understanding of the laboratory response of sands and silty sands under cyclic loading, only very limited research has been undertaken on this subject with regard to the behaviour of fine-grained soils (silts). In the liquefaction evaluation of fine-grained soils, engineers mostly depend on empirically-based criteria that relate the performance of these soils in past earthquakes with index properties such as the clay content, liquid limit, and water content. Recent studies indicate that some soils that are classified as not susceptible to liquefaction based on empirical criteria, in fact, has the potential to suffer liquefaction during cyclic loading. As a part of an ongoing research program on the cyclic response of fine-grained soils, the applicability of empirically-based criteria is reviewed considering the results from carefully conducted cyclic direct simple shear tests on undisturbed samples of silt from the Fraser River Delta, British Columbia, Canada. The review also includes the comparison of results with some observations on fine-grained tailings and some published data.
