In the Chinese southeast coastal areas, most of the rail transit infrastructures are built on the soft soil. Infrastructures construction and operation including high speed railway or urban railway system require a good understanding of the behavior of the soft soil subject to the static and dynamic loading induced by the infrastructure.
Extreme climatic events in the 21st century threaten the resilience of geotechnical engineering structures. Low-permeability barriers are at a particularly high risk of inundation under flooding or cracking during droughts, compromising the barriers and permitting contamination of the surrounding ground.
The objective of this research is to investigate the behavior of Dunkerque sand under undrained triaxial cyclic loading using the discrete element method (DEM).
