Performance Analysis of Northern Infrastructure Affected by Climate Change

In this project, considering the rate-dependent behavior of permafrost, a multiphysics-based hazard ??assessment tool will be developed to investigate the life-cycle performance of infrastructure subject ?to ?different seasonal climate projections and climate change scenarios. For this purpose, first, an ?advanced thermo-elasto-viscoplastic (TEVP) constitutive model is being developed based ?on the ?framework of critical state soil mechanics to thoroughly capture the thermal creep ?behavior of ?permafrost. The TEVP constitutive model can thoroughly capture ?the thermal creep behavior of ?permafrost and the rate-dependent deformation of degrading ?permafrost. Afterward, the ?constitutive model will be implemented into a Finite Element (FE) ?software called DISROC to develop a ?multi-dimensional THM numerical platform that can be used as a robust hazard ?assessment tool in the ?life-cycle performance assessment and climate-resiliency analysis of ?northern infrastructure (physical ?asset) ?in permafrost regions.?
