The meaning of effective soil parameters for determining of the bearing capacity of cohesive soils

Budownictwo i Architektura, 2014
The paper presents the analysis of the bearing capacity of cohesive soils, which was calculated based on the PN-EN-1997-1 methodology. This computations take into account the effect of pore water pressure on the soil strength parameters.

Evaluation of local damping effect on static and dynamic behaviors of granular materials using DEM modeling [PDF]

مهندسی عمران شریف, 2022
Frictional sliding may not be sufficient for the stability of a system. In almost all models in the Discrete Element Method (DEM), a local non-viscous damping is used to balance the system by applying a damping force with a magnitude proportional to the ...

Mechanical Behavior of Triaxial Geogrid Used for Reinforced Soil Structures

Advances in Civil Engineering, 2021
Geosynthetics-reinforced soil (GRS) structures have been widely used for the prevention of geological hazards. As a recently introduced product, the triaxial geogrid has been confirmed to provide improved performance due to the more stable grid structure.

Failure criterion for soft rocks considering intermediate principal stress

International Journal of Mining Science and Technology, 2021
The significant differences between hard rocks (more brittle) and soft rocks (more ductile) may suggest the use of different failure criteria. A strength criterion for soft rocks that includes intermediate principal stress was proposed. The new criterion

An Incorporating Pore Water Pressure Constitutive Model for Overconsolidated Clay and Calibration of Transient FE Parameters

Journal of Marine Science and Engineering
The simulation accuracy of triaxial tests for oversolidated clay in transient finite element analysis is affected by soil constitutive model, permeability coefficient, overconsolidation ratio, shear rate and mesh size.
