Design Problems in Soil Liquefaction

Evaluating this possibility requires a knowledge of the residual strength of the liquefied soil, and, while laboratory test procedures have been developed for determining such a strength, it is suggested that the establishment of relationship between this property of a soil, as determined by field performance studies, and some in situ soil characteristic, such as penetration resistance, may provide the most practical method for evaluating residual strengths in cases where such values are required. Available data based on case studies is summarized and plotted in chart form for this purpose.
