Abstract

A thorough statistical study of the possible correlations of engineering properties of the Gulf of Mexico clays was conducted. A volume of data was collected from which correlations were derived through the use of a Univac 1108 electronic computer. The results are shown in the form of regression equations with the coefficient of correlation and standard error of estimate given for each equation. It is concluded that the compression index and remolded shear strength are fairly predictable quantities; while the undisturbed shear strength, determined by unconfined compression tests, cannot be predicted with much accuracy from the index properties of the clay. The benefits and usefulness of statistical correlations as well as their limitations are discussed.
