Measurement of In-Place Relative Density in Coarse Grained Alluvium for Comparison to Penetration Tests

This paper summarizes results of investigations into coarse grained alluvial soils at several Bureau of Reclamation dams. In-place density tests have been performed in coarse grained deposits to measure relative density. Relative density data can be correlated to liquefaction resistance and to penetration testing. Penetration tests are the primary method of determining liquefaction resistance.
