An approach to evaluation of field CPTU dissipation data in overconsolidated fine-grained soils
Download1999
Campanella, R., Robertson, P. K., Woeller, D., Sully, J.
Abstract: Dissipation of excess pore pressures during piezocone testing in firm to stiff overconsolidated fine-grained soils provides data curves that cannot be interpreted using published theoretical solutions. Available solutions are based on either cavity-expansion or strain-path methods,...

An overview of soil heterogeneity: quantification and implications on geotechnical field problems
Download2003
Elkateb, T., Chalaturnyk, R., Robertson, P. K.
Abstract: Engineering judgment and reliance on factors of safety have been the conventional tools for dealing with soil heterogeneity in geotechnical practice. This paper presents a review of recent advances in treating soil variability. It presents the implications of geostatistical techniques...

Robertson, P. K., Skopek, P., Sego, D. C., Morgenstern, N. R.
Abstract: Loose cohesionless saturated materials have proved responsible for a number of serious or catastrophic flow slides. Liquefaction failures with no obvious triggering mechanism have also been recorded. This phenomenon of sudden liquefaction without a presence of cyclic shear stresses is...

Detection of shear zones in a natural clay slope using the cone penetration test and continuous dynamic sampling
Download2000
Mahmoud, M., Woeller, D., Robertson, P. K.
Abstract: The detection of shear zones along which a mass of soil is moving is essential for understanding the state of stability of natural slopes. Weaker zones in clay soils can be identified from low values of cone penetration test (CPT) tip resistance measured during penetration. This paper...

Morgenstern, N. R., Robertson, P. K., Imam, S. M. R., Chan, D. H.
Abstract: In very loose sand, the ratio M-p of shear stress to mean normal stress at the peak point of the undrained effective stress path (UESP) is very close to the stress ratio M at the peak point of the capped yield surface. Stress ratios M-p can therefore be used in constructing yield...

Zhang, G., Brachman, R. W. I., Robertson, P. K.
Abstract: An integrated approach to estimate liquefaction-induced ground settlements using CPT data for sites with level ground is presented. The approach combines an existing CPT-based method to estimate liquefaction resistance with laboratory test results on clean sand to evaluate the...
