PREDICTION OF SHEAR STRENGTH OF SAND BY USE OF DYNAMIC PENETRATION TESTS

Texas cone penetrometer tests were conducted at six sites in the middle and upper Texas gulf coast region. The soils tested were cohesionless and included poorly graded sands and silty sands. The direct-shear test method was used to determine the effective angle of internal shearing resistance of the soils, and an empirical relationship was used to obtain standard penetration test values from the measured Texas cone penetrometer test data. The standard penetration test N-values of fine and silty saturated sands were corrected to account for the development of pore pressures during driving. Both the Texas cone and the standard penetration test N-values were correlated with the shear strengths and with the effective angles of internal shearing resistance of the sands. The new correlations were compared with existing correlations commonly used in the geotechnical profession, and it was found that the currently used relationships between the N-value and the effective angle of internal shearing resistance are a lower bound for these test data.
