A Study on the Correlation between Standard Penetration Resistance Value and Static Cone Penetration Resistance Value of the Soft Ground Subsurface of Yongdong Area

We have conducted standard penetration tests and static cone penetration tests that are widely used the land base examination on the soft ground subsurface of Yongdong area, and examined the correlation between them. We have also made a comparative analysis of the correlation between the indoor tests on the materials collected on the site and on-the-spot penetration tests. The results are as follows : The relationship between Standard Penetration Test N-value and Dutch Cone Tset show for organic soil, for clay, for silt, for silty sand, and for sand. In this case of sand increases when the soil particles are larger. The relationship between standard penetration test N-value and Unconfined Compression Strength show for organic soil, for clay, and for silt.
