New correlations between various CPTU factors, undrained shear strength and overconsolidation ratio have been developed for soft to medium stiff clays. The correlations are based on comparing the CPTU results against undrained traxial compression strength and preconsolidation pressure determined on block samples of very high quality taken with the ...

Liquefaction potential of silts from CPTu
Canadian Geotechnical Journal, 2007Silt tailings (slimes) are difficult materials to test in that, like sands, it is extremely difficult to obtain undisturbed samples and subsequently re-establish them in a triaxial cell for element testing in a laboratory in anything approaching their in situ condition.

CPTU dissipation behavior of overconsolidated clay
2005In normally clays and silts, excess pore pressures due to piezocone penetration show a monotonically decreasing response with time, but dissipation tests performed in heavily overconsolidated soils show dilatory behavior. Therefore, available solutions proposed for normally consolidated soils do not adequately evaluate the response of pore water ...

Estimating clay undrained shear strength using CPTu results
Proceedings of the Institution of Civil Engineers - Geotechnical Engineering, 2009Estimation of the undrained shear strength su of clays using piezocone penetration test (CPTu) results has been based mainly on the cone factor Nk. In this study a new CPTu-based method for estimating su is proposed and evaluated. It is aimed at reducing uncertainties in the estimation of su and enhancing the application of CPTu results.

Variation for Soil Stress on CPTU Model Test
Applied Mechanics and Materials, 2010Through a series of Piezocone Penetration Test (CPTU) model tests with saturated clay soil, by CPTU probe penetrating soil stress measured by soil pressure mini-cells embedded into soil has been acquired, the variation rules of soil stress by penetrating has been analyzed, the results show that with probe close to the second cell layer, the stress ...

CPTu-based enhanced UniCone method for pile capacity
Engineering Geology, 2016The UniCone direct piezocone method by Eslami and Fellenius (1997) for evaluating the axial capacity of pile foundations is reviewed and improved means of evaluating the soil resistance factors are recommended. This method uses all three piezocone penetration test (CPTu) readings in a soil behavioral type (SBT) classification chart and provides ...
