Implementation of research findings - drilled shaft investigation (FHWA-OK-81-06) 602

Abstract

The purpose of this report is to establish soil properties of Oklahoma flood plain (alluvial) soils for drilled shaft design. Also, to establish a correlation between shear strength (Su) obtained from unconfined compression test and N values obtained from both Texas Cone Penetrometer and Standard Penetration Test for Oklahoma flood plain soils. This study evaluates a variety of alluvial soils at seven sites throughout the state of Oklahoma. For each site Texas and Standard Penetrometers were used to find N values for different types of soils in flood plain deposits.
