Correlation between SPT and CPT for Sandy Soils in Port Sudan City using the Linear Regression Model

In geotechnical engineering, in-situ tests, like standard penetration test (SPT) and cone (CPT), are essential to evaluate the underground conditions. SPT is a frequently used approach, while CPT considered one of best exploration apparatuses. However, there demand for correlation SPT-CPT that can be in design. This research aimed find relationships between test’s blow count (N) tip resistance (qc) different groups sandy soils Port Sudan city, Sudan. The data this study was attained from numerous projects conducted city identify values tests were compared tried generate specific statistical data. correlations established qc N various soils. Uphill linear wear found These results interpreted based on their coefficients. proposed formulas predict three soil groups, with high coefficient. Besides, qc/N ratios calculated groups; current agree those published literature less values.
