Climate Effects on Desiccation Cracking of Soils

Session ID#: 76447

Session Description:
Desiccation cracking is the crack development at the soil surface and subsequent propagation in depth as a result of shrinkage due to the reduction of the water content through constantly changing weather-driven processes. The desiccation of cohesive soils leads to undesirable impact on the mechanical, hydrological, thermal, and physico-chemical soil properties. For instance, desiccation cracking can lead to a decreased strength in cohesive soil which in turn can cause uneven settlement and failures. The cracking also results in a dramatic increase in the permeability of clayey soils, which is particularly problematic when clay is used as a liner and cap for both landfills and hazardous waste storage. Therefore, the understanding of climate effects on desiccation cracking is paramount to both safety, structural, and environmental issues.

This session aims at bringing together researchers and practitioners to share new results on this topic. Theoretical, numerical, and experimental contributions are welcome.
