Centrifuge cone penetration tests in sand

Application of Cavity Expansion Theory in Predicting Centrifuge Cone Penetration Resistance

In this paper, a simple model for the prediction of centrifuge cone penetration tip resistance in sand is presented. The proposed method, which relates the tip resistance to the pressure to expand a spherical cavity, refines and simplifies Greeuw’s original equations. The method assumed the failure mode of a spherical cavity expansion pressure given as a function of shear stiffness, angle of fr...

Nationwide lithological interpretation of cone penetration tests using neural networks

The Geological Survey of the Netherlands (GSN) systematically produces 3D stochastic geological models of the Dutch subsurface. These voxel models are regarded essential in answering subsurface-related questions on, for example, aggregate resource potential, groundwater flow, land subsidence hazard and the planning and realization of large-scale infrastructural works. GeoTOP is the most recent ...

Interpretation of cone penetration tests — a unified approach

The electric cone penetration test (CPT) has been in use for over 40 years and is growing in popularity in North America. This paper provides some recent updates on the interpretation of some key geotechnical parameters in an effort to develop a more unified approach. Extensive use is made of the normalized soil behaviour type (SBTn) chart based on normalized cone resistance (Qt) and normalized...

evaluation of cone penetration resistance in loose silty sand using calibration chamber

this paper highlights the effect of silt content on cone tip resistance in loose silty sand. in this study, twenty-seven cone penetration tests are performed in saturated silty sand samples with several different silt contents ranging from 10 to 50 percent. the samples are consolidated at three overburden stresses including 100, 200 and 300 kpa. it is shown that, as the silt content increases, ...
