Estimation of Standard Penetration Number with Index Properties of Cohesive Soil

Abstract

The standard penetration number is obtained from the standard penetration test, which is one of the soil engineering investigations. The standard penetration number can be used to classify soil according to soft or hard and loose or dense for cohesive and cohesionless soil, respectively. In addition, it can approximately represent the undrained shear strength, bearing capacity, and settlement of the foundations. This article presents the estimations of the standard penetration number of cohesive soil with standard properties, using empirical relationships and statistical methods. The results show that the standard penetration number has a statistically significant relationship with basic soil properties. Also, this study can successfully and precisely estimate the standard penetration number with an R-squared of 0.996
