Coupled finite difference and discrete element method for modelling the underground stopes backfilled with the cemented rockfill
DownloadSpring 2023
Backfill columns and the adjacent rock pillars at the underground backfilled stopes are not isolated but mutually supported. Stress transmission and energy alternation occur between them ceaselessly due to the ubiquitous mechanical interactions at the frictional-bonded interfaces between backfill...

Predictive Method for Pipeline Strain Demand Subject to Permanent Ground Displacements with Internal Pressure & Temperature
DownloadFall 2022
Pipelines subject to ground deformations generated by geohazard loads carry high importance on pipeline analysis, design, and assessment due to risk of structural damage or failure. Additionally, internal pressure and temperature variation within an operating pipe induce additional strains in...

Stress- and strain-based reliability assessment of pipelines subjected to internal pressure and permanent ground movement
DownloadFall 2023
As a critical member of infrastructural lifeline, pipelines fulfill a vital role in energy delivery across long distances from source to market. Pipelines at service can be exposed to a wide variety of loads depending on the environment and the area of application. Internal pressure and ground...
