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 ...

An Update on Pile-CPTu Direct Correlations
Ports 2013, 2013The axial pile capacity can be estimated from the cone penetration test (CPT) using either indirect methods or direct methods. The indirect methods employ a dual-phase methodology of estimating the geoparameters for evaluating the shaft and base resistance (fp and qb, respectively) of the pile capacity.

Seismic CPTu to Assist the Design on Existing Foundations
Soil Dynamics and Earthquake Engineering, 2010Limited space in urban area makes it attractive to reuse the existing foundation. This paper presents a case study on the use of seismic piezocone penetrometer (SCPTu) to conduct parallel seismic test for the determination of the length of unknown foundation.

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 Classification Diagrams for Identification of Sensitive Clays
2017When dealing with slope stability considerations in deposits where sensitive and quick clays might be encountered it is vital to map the extent of these clays. For the geotechnical engineer, the cone penetration test with pore pressure measurement (CPTU) is a powerful tool in this respect.
