Abstract: This paper presents the correlation analysis between Standard Penetration Test (SPT), blow count (N) value, and shear strength parameters of residual cohesive soils from Huanggang Eroded Ridge formations. The data used in the analyses are from the geotechnical exploration of nine (9) projects. A empirical relationship between the SPTN value and the strength parameters, cohesion c and internal friction angle,  φ, are obtained through the regression analysis of 99 N values and 102 tested samples.
