Reinforcement of Poorly Draining Soils

Participants: YoungCheol Kang, Sidnei Teixeira, Sean Sanchez

Description: This project involves pullout of geogrid from saturated and unsaturated cohesive soils. In addition, the effect of in-plane drainage, used along geogrid reinforcement, on the generation of pore pressures during shearing is investigated.
