Distributed soil displacement and pressure associated with surface loading
Soil compaction is an inevitable result of agricultural practices. It alters physical properties of soil and tends to be undesirable as it adversely affects water and nutrient penetration. Furthermore, additional energy is spent to till the soil. Although a tremendous amount of research has been …

Finite element analysis of multipass effects of vehicles on soil compaction
… the multipass effect of rubber-tired vehicles on soil compaction. The wheel-soil interaction was modeled as an axisymmetric problem by approximating the elliptical wheelsoil contact area with an equivalent circular area. A hyperbolic stress-strain relationship was used to model the nonlinear …

Particle labeling for sediment source tracking on hillslopes
Soil erosion on hillslopes is a dynamic process, which evolves temporally and spatially. Sediment source tracking can be used to identify the areas within a watershed where erosion is greatest. This study evaluated three sediment source tracking techniques, rare earth element (REE) particle …

Response of piled buildings to the construction of deep excavations
… research provides insight into mechanisms of soil-structure interaction for piled buildings adjacent to deep excavations to be used in the design and monitoring of deep excavations in urban areas. Most methods to assess building response have originally been developed for tunnelling projects …

Experimental and numerical investigations to assess the behaviour of a buried pipeline in areas with high geological instability
Ground displacements such as landslides, fault movements, soil liquefaction which may be caused by seismic activity are one of the most dangerous phenomena that can involve buried pipelines, e.g. for oil and gas transportation, or water and sewage. This aspect is currently an important part of …

Timber Harvesting and Site Preparation Effects on Soil Quality for Loblolly Pine Growing on the Lower Coastal Plain of South Carolina
… of nearly-level topography, poorly-drained soils, and high rainfall, which results in a perched water table in some soils that inundates the surface several times each year. Harvesting timber under wet site conditions often results in extensive soil compaction, rutting, soil displacement, …

Contribution to kinematic and inertial analysis of piles by analytical and experimental methods
The problem of pile - soil interaction is examined in the Thesis at hand by means of both theoretical analyses and experimental investigations. Pile foundations in seismically prone areas are subjected to both direct loading, such as axial and lateral forces imposed at their heads, resulting from a …

Integral bridge abutment and backfill behaviour
… of the bridge deck leads to the accumulation of soil strain — known as strain ratcheting — which results in increased lateral earth pressures along with settlement at the bridge approach. Uncertainty surrounding strain ratcheting is reflected through design restrictions. This research …
