Displacement finite element analysis is performed for a cone-penetration test in cohesionless soils. By modelling finite strain in the soil and large scale sliding at the penetrometer–soil interface, a more realistic penetration process is simulated in which the penetrometer is assumed to be rigid and the soil is assumed to be an elastic-perfect-plastic continuum obeying the Mohr–Coulomb criter...

Understanding and assessing the spatial extent of liquefaction hazard requires the spatial dependence of geotechnical properties to be taken into account. In this work, novel multiscale random field models will be developed to characterize and quantify spatial variability of geotechnical parameters across scales. Such models will then be integrated with a simplified procedure for the probabilis...

Due to the introduction of Eurocode 8, the structural design for seismic and dynamic effects has become more significant in Hungary. This has emphasized the need for more effort to describe the behavior of structures under these conditions. Soil conditions have a significant effect on the response of structures by modifying the stiffness and damping of the soil-structural system and by modifyin...

soil compaction is an important aspect of agriculture and different methods are available to measure this parameter. one method is called the cone index; measuring the force required per unit area for penetration of a standard steel cone into the ground. cone penetrometers are used for cone index measurement. in this study, a tractor mounted, hydraulically-operated penetrometer was designed, bu...

In this paper, the discrete element method (DEM) is coupled with Lattice Boltzmann (LBM) to model cone penetration test (CPT) of a saturated granular media. The numerical was calibrated using one-dimensional (1D) consolidation theory. results obtained from 1D simulation showed good agreement analytical equation that proposed by Terzaghi. A series LBM–DEM simulations were carried out understand ...

A solution is developed for the evolution of buildup, steady, and postarrest dissipative pore-fluid pressure fields that develop around a finite-radius conical penetrometer advanced in a saturated linearly elastic porous medium. The analog with cone penetrometer testing is direct and is used to enable continuous distributions of permeability and diffusivity to be determined with depth. This ana...

In the simple buildings, shallow foundations can be used to support construction above them. This foundation has various types, including type of footplate which calculated using Terzaghi equation. equation, it requires dimension parameters footing and soil material such as cohesion volume weight laboratory testing obtain it. Meanwhile, Schmertmann provides an equation bearing capacity factor i...
