Correlations of Soil Properties with Index Properties

1.0 INTRODUCTION

The correlation of soil properties with its index properties have been used by engineers to estimate the engineering properties of a soil if the index properties are known. This is especially important where there is inadequate information from the site and laboratory investigation results or where results need to be validated with the existing literature values in order to determine the appropriate soil design parameters.

Many renowned researchers such as Carrier and Beckman (1984), Carter and Bentley (1991), Henkel (1959), Houlsby and Whithers (1988), Skempton (1957), and Wroth and Wood (1976) have developed correlations that relate engineering properties of soil with its index properties. Since these correlations were made there had been advances in the field and laboratory testing for the determination of both index and engineering properties of soil. This study attempts to systematically review and synthesise the existing correlations between the permeability, shear strength, and compressibility of soil with Atterberg limits and make recommendations for modifications where necessary based on the current geotechnical engineering practice and development of soil testing. Since the method of performing both the index tests and engineering parameter tests has a direct influence on the correlation of the index properties with the engineering properties.

This chapter covers the review of related literature, foreign and local, published articles including journals and other periodicals such as being available and relevant to the subject under investigation. In this wise therefore, contemporary materials, opinions and presentations shall be decisively employed and reviewed. A total of 150 published articles...
