Artificial intelligence algorithms for prediction of cyclic stress ratio of soil for environment conservation

open access: yesEnvironmental Challenges, 2023
Civil Engineering structures are constantly subjected to environmental forces and changes around the surroundings hence a strong need for assessment of the interaction and predictive measures that lead to pro-active actions towards the structural safety ...

Assessment of cyclic deformation and critical stress amplitude of jointed rocks via cyclic triaxial testing

open access: yesJournal of Rock Mechanics and Geotechnical Engineering, 2023
Jointed rock specimens with a natural replicated joint surface oriented at a mean dip angle of 60° were prepared, and a series of cyclic triaxial tests was performed at different confining pressures and cyclic deviatoric stress amplitudes.

Experimental study on damping ratio of overconsolidated clay under different cyclic confining pressures

open access: yesYantu gongcheng xuebao, 2022
Traffic loading is usually simulated by single cyclic deviator stress. However, the vertical normal stress and horizontal stress acting on the soil elements are all varied cyclically under the traffic loading.

Thermal effects on one-way cyclic behaviour of clay-structure interface [PDF]

open access: yesE3S Web of Conferences, 2020
In energy geostructures, which exploit the heat in soil using earth contact elements, the interface is subjected to cyclic thermo-mechanical loads. Monotonic and cyclic constant-volume equivalent-undrained (CVEU) direct shear tests were performed on clay-

Post-cyclic strength behaviors of undisturbed soft soils with different degrees of reconsolidation

open access: yesYantu gongcheng xuebao, 2021
The soft soil after cyclic loading is often in an intermediate state between unconsolidated and fully reconsolidated after a period of time, which can be described by the concept of degree of reconsolidation. At present, there are few studies considering
