Cyclic Behavior of Tianjin Soft Clay under Intermittent Combined-Frequency Cyclic Loading

International Journal of Geomechanics, 2020
Abstract Subgrade soft clays are subjected to intermittent changeable-frequency cyclic loading and exhibit complex dynamic reactions compared with those under single-frequency cyclic loading.

Cumulative permanent strain and critical dynamic stress of silty filler for subgrade subjected to intermittent cyclic loading of trains

Bulletin of Engineering Geology and the Environment, 2021
The long-term loading of the trains on the subgrade in service is the cyclic loading when the train passes and the intermittent stage when there is no train passing. However, in most studies, continuous loading was used to investigate the dynamic characteristics of a subgrade soil, which ignores the effect of loading intermittence.

Dynamic behaviors of fine-grained subgrade soil under single-stage and multi-stage intermittent cyclic loading: Permanent deformation and its prediction model

Soil Dynamics and Earthquake Engineering, 2021
Abstract The realistic simulation of the train dynamic loading is essential to the study of the dynamic behaviors and long-term stability of the railway subgrade. Considering the loading intermittence caused by the time interval between adjacent trains and the increasing dynamic stress response of the subgrade caused by the increasing axle load and ...

The effects of cyclic loading on the reconsolidation behaviours of marine sedimentary clays under intermittent drainage conditions

Soil Dynamics and Earthquake Engineering, 2021
Abstract The reconsolidation settlement of marine sedimentary clay subgrade subjected to cyclic dynamic loading under intermittent drainage conditions needs to be further studied. In this study, a series of triaxial tests was conducted on natural Wenzhou soft clays to investigate the reconsolidation responses induced by staged cyclic loading under ...

Radial drainage and consolidation of soft soil subjected to intermittent cyclic loading

Géotechnique
The rail network invariably encounters soft subgrades consisting of shallow estuarine clayey deposits. Cyclic loading generated by the passage of trains causes deformation and corresponding development of excess pore water pressure (EPWP), which dissipates during the rest periods between two consecutive trains. This paper presents an experimental study
