Seasonal weather variations have a profound effect on the integrity of cohesionless soil slopes in Canadian Prairies owing to prevalent semi-arid continental climate. The primary contribution this research is development transient and two-dimensional stability model that fully coupled with hydraulic thermal flows. was used predict factor safety (FS) for two slope geometries (18 m height 26 heig...

The Balsum Bud Cove Formation of the Snooks Arm Group, eastern Baie Verte Peninsula, Newfoundland contains intervals of epiclastic mafic volcanic debrites characterized by textures indicative of gravity flow evolution in a submarine setting. These proximal to distal and aggradational deposits record a downslope change from debris avalanche to cohesionless debris flow processes. This change invo...

The Pliocene Loreto basin is an asymmetrical half graben located on the eastern margin of Baja California Sur, Mexico, which formed by rapid subsidence along the dextral-normal Loreto fault. The southern Loreto basin contains numerous, well exposed coarse-grained Gilbert-type fan deltas that were derived from the footwall of the Loreto fault. Detailed sedimentological study of individual forese...

Soil conditioning is a key factor in increasing tunnel face stability and extraction efficiency of excavated soil when excavating tunnels using an earth pressure balance (EPB) shield boring machine (TBM). Weathered granite soil, which abundant the Korean Peninsula (also Japan, Hong Kong, Singapore), has different characteristics than sand clay; it also particle-crushing characteristics. Conditi...

In this paper, limiting force profile for laterally loaded rigid piles in sand and is differentiated from the on-pile force profile, from which elastic-plastic solutions are established and presented in explicity expressioins. Nonlinear responses of the piles are characterized by slip depths mobilized from mudline and the pile-tip. At the states of tip-yield and rotation point yield, expression...

We present simple models of particulate materials whose mechanical integrity arises from a jamming process. We argue that such media are generically “fragile”, that is, they are unable to support certain types of incremental loading without plastic rearrangement. In such models, fragility is naturally linked to the marginal stability of force chain networks (granular skeletons) within the mater...
