Study on the Correlation between Cone Resistance and Soil Density Using Centrifuge Robot CPT

Abstract

Density is one of the most important soil parameters. However, it is difficult to measure the density of soil model during centrifuge in flight. The cone penetration test (CPT) with robot provides a useful tool to determine the soil density of different models, as the cone resistance is closely related to soil density. This paper presents the correlation between cone resistance and relative density of sand, by doing centrifuge tests with robot CPT. Based on the test results, a formula that describes the correlation between cone resistance and sand relative density of Fujian standard sand is proposed for IWHR CPT attached to centrifuge robot.
