Determination of Geotechnical Parameters of a Heterogeneous Tropical Soil Deposit Through Different Penetration Rate CPTu Data
Abstract
Assessing soil properties through geotechnical tests is a crucial activity to understand its behaviour. Field tests serve as a good approach to characterize the geotechnical behaviour of materials according to their in-situ condition. However, the interpretation of these tests often [...]

Investigation of the Relationship Between CPT Cone Resistance and Relative Density for a Range of Granular Soils
Abstract
This paper presents an investigation of the effects of the properties of reconstituted granular soils on the relationship between CPT cone resistance (qc) and friction angle. The results from a large number of calibration chamber tests conducted at a number of stress levels involving [...]- 0

Application of two analytical CPTU solutions to sensitive clay in Québec
Abstract
A recent series of CPTU soundings in sensitive clay at the Louiseville Quebec test site has been published, allowing for the application of two closed-form analytical solutions based on: (1) effective stress limit plasticity and (2) hybrid cavity expansion-critical state methods. [...]- 0

Stress History and Effective Shear Strength Parameters Evaluation of a Dilative Stiff Clay
Abstract
The Cone Penetration Test (CPTu) can be used to evaluate the soil behaviour and properties through correlations (empirical and/or analytical), and the results must be compared to laboratory tests to be validated. This paper presents the evaluation of the effective friction angle (φ’) [...]- 0

Soil Variability From High-Resolution S-Wave Full-Waveform Inversion: Deriving Reliable Cone-Tip Resistance From Vs for Geotechnical Evaluations
Abstract
Capturing the spatial variability in soil is crucial for ground response analyses in the context of seismic hazard mitigation. The lateral variability in thickness and properties of the different soil layers is one of the main factors that determines the variability of the ground [...]- 0

Cone Penetration Test-Based Correlations to Forecast Critical State Parameters
Abstract
In critical state soil mechanics, the critical state refers to the combination of effective stress and void ratio (e) at which a soil continues to shear with no change in effective stress, shear stress, and e. The phenomena can be visualized using the critical state line (CSL). The [...]- 0

Calibration and Test Bed Simulation of a 40 Cm2 Cptu Cone
Abstract
In cone penetration testing (CPT) an electronic penetrometer is pushed at a constant rate into penetrable soils and cone bearing (qc), sleeve friction (fc) and dynamic pore pressure (u) are recorded with depth. The measured qc, fs and u values are utilized to estimate soil type and [...]- 0
