A New Bonding Model for the Particulate Simulation of Bio-Cemented Sand (with a Side Excursion on Percolation in Granular Mixtures)

Creator:

Khoubani, Ali

Abstract:

Bio-cementation is a promising method for the liquefiable mitigation of loose saturated sands. In the improvement process a bacterium that can be found naturally in soil deposits is fed urea. The bacterium consumes and breaks down the urea to form ammonium and carbonate. In the presence of calcium, calcium carbonate...

Numerical Simulations and Microscale Analyses of Offshore Anchor-Granular Material Systems

Creator:

Zhang, Nan

Abstract:

Anchoring systems are used to hold floating offshore devices (e.g., energy devices, oil platforms) to keep them on their stations. Anchors are embedded into the seabed soils. In some cases, the interface shear between anchor and seabed soils together with anchor self-weight provide the holding capacity of the anchoring systems....
