  • Essay / Correlations of Soil Properties with Index Properties

    1.0 INTRODUCTIONThe correlation of soil properties with its index properties has been used by engineers to estimate the engineering properties of a soil if the index properties are known. This is particularly important when information from site and laboratory investigation results is insufficient or when results need to be validated with existing literature values ​​in order to determine 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 linking the properties soil techniques to its indicator properties. Since these correlations were established, advances have been made in field and laboratory testing for the determination of soil index and engineering properties. This study attempts to systematically examine and synthesize the existing correlations between permeability, shear strength and compressibility of soil with Atterberg limits and to make recommendations for modifications if necessary based on current engineering practices geotechnical and soil testing development. Since the method of performing index tests and engineering parameter tests has a direct influence on the correlation of index properties with engineering properties. This chapter covers the review of related literature, foreign and local, published articles, including journals and other periodicals as available and relevant to the subject under investigation. In this way, contemporary documents, opinions and presentations must be used and examined decisively. A total of 150 articles published...... middle of paper ...... month.
