Purpose and Background
These presentations were recorded at the Geo-Congress 2026.
Meshless Numerical Modeling of Vane Shear Test (13 minutes)
This presentation explores the application of meshless numerical methods to simulate the vane shear test, which is commonly used to determine the undrained shear strength of soft soils. Traditional finite element methods rely on predefined meshes, which can struggle with large deformations and soil failure. Meshless modeling overcomes these limitations by allowing particles or nodes to move freely without mesh distortion. The study demonstrates how this approach can more accurately capture soil behavior during shear. Results are compared with experimental data to validate the model’s performance. The presentation also discusses computational efficiency and modeling challenges. Overall, the approach provides a more robust tool for analyzing complex geotechnical problems.
Measurement of Soil Thermal Conductivity Using a Novel CPT Module: An Update (13 minutes)
This presentation introduces a novel cone penetration test (CPT) module designed to measure soil thermal conductivity in situ. Thermal conductivity is a critical parameter in applications such as geothermal systems, buried cables, and energy foundations. Traditional laboratory methods can be time-consuming and may not represent in-situ conditions accurately. The new CPT module integrates thermal sensors into the probe, allowing real-time measurements during penetration. The presentation provides updates on field testing and calibration procedures. Results demonstrate improved efficiency and reliability compared to conventional methods. This innovation enables better design and performance of thermally sensitive infrastructure.
Undrained shear strength from CPTU in soft clay, stiff till, and soft rock in the UK (13 minutes)
This presentation examines methods for estimating undrained shear strength using piezocone penetration test (CPTU) data across different soil types in the UK. The study includes soft clay, stiff till, and soft rock, each presenting unique challenges for interpretation. Empirical correlations are evaluated to determine their accuracy in predicting shear strength. The role of pore pressure measurements in improving estimates is emphasized. Differences in soil behavior highlight the need for soil-specific calibration factors. Case studies illustrate how CPTU data can be effectively used in design. The findings contribute to more reliable and efficient geotechnical site characterization.
Effect of Particle Refinement Method Parameters in Discrete Element Method Simulations: Cone Penetration Test Example (11 minutes)
This presentation investigates the effect of particle refinement parameters in discrete element method (DEM) simulations, using cone penetration testing as a case study. DEM models soil as an assembly of discrete particles, enabling detailed analysis of micromechanical behavior. Particle refinement plays a key role in determining simulation accuracy and computational efficiency. The study evaluates how different refinement strategies affect penetration resistance and stress distribution. Results show that improper parameter selection can lead to inaccurate predictions. The presentation highlights best practices for balancing accuracy and computational cost. These insights improve the reliability of DEM simulations in geotechnical engineering.
