Effects of Differential Subgrade Settlement on Slab Track Deformation Based on a DEM-FDM Coupled Approach

open access: yesApplied Sciences, 2021
Slab track structures become deformed under the effects of differential subgrade settlement. According to the properties of the China Railway Track System (CRTS) II slab track on a subgrade, a three-dimensional (3D) coupled model based on both the ...

Investigation of Water and Soil Migration and Mud Pumping of Subgrades under Traffic Load

open access: yesAtmosphere, 2023
Atmospheric precipitation leads to the increase of moisture in the subgrade. The moisture and soil migration in subgrade is a key scientific problem in evaluating the service performance of the subgrade and resolving or preventing mud pumping.

The Cooperative Control of Subgrade Stiffness on Symmetrical Bridge–Subgrade Transition Section

open access: yesSymmetry, 2022
In the field of civil engineering and architecture, the concept of symmetry has been widely accepted. The bridge can be treated as a typical symmetrical structure of civil engineering buildings. Among them, the Subgrade can be identified as an important part to bear the vehicle loads.

Subgrade Stabilization Alternatives [PDF]

open access: yes, 2020
Recent research has shown that the subgrade soil type and its engineering properties govern the performance of the pavement, especially for clayey soils. However, current application of the Pavement_ME in Indiana does not fully account for the changes of type of soil and stiffness that may arise with treatment.
