Abstract

The paper presents the studies performed as part of the liquefaction potential evaluation for Arcadia Dam. The evaluation was performed by the Tulsa District, Corps of Engineers, using a modification of the "Simplified Procedure" developed by H. B. Seed. A discussion of the various decisions, judgements and procedures used to adapt the required studies to the site specific conditions is presented along with a description of drilling, sampling, sample handling, and laboratory testing. The most significant finding from the evaluation is that a useful relationship exists between standard penetration test (SPT) blow count values, laboratory cyclic shear strength and soil grain size. This relationship enabled the SPT data obtained in the silty sands and silts present at Arcadia to be used with the simplified procedure which is based on blow count data obtained in relatively clean sands.
