Performance and Assessment of Rehabilitated Steel Culverts
(2016-10-25)This thesis explores the effects of rehabilitation on the structural performance of corrugated steel culverts. A full-scale laboratory experiment investigated the effects of grouted slip-liners on the performance of two ... -
Performance of Geomembranes to Contain PCBS, Brine and Reverse-Osmosis Water
Accelerated ageing tests are used to examine the performance of geomembranes in three applications. The thesis examines a broad range of geomembranes produced over a time span of 30 years and highlights the progress made ... -
Performance of Geosynthetic Clay Liners in Cover, Subsurface Barrier, and Basal Liner Applications
(2014-02-28)The use of geosynthetic clay liners (GCLs) as (i) covers for arsenic-rich gold mine tailings and landfills, (ii) subsurface barrier for migration of hydrocarbons in the Arctic, and (iii) basal liner for sewage treatment ... -
Performance of Geosynthetics for Remediation of Hydrocarbons and Emerging Contaminants
Diffusion of volatile organic contaminants through a thin (0.508 mm) seven-layer geomembrane including EVOH was evaluated using laboratory diffusion tests and compared to traditional polyethylene geomembranes. Using the ... -
The Performance of Reinforced Concrete Pipe Joints under Differential Ground Settlement
Leakage from reinforced concrete pipe joints has negative environmental impacts and can compromise the sewer or culvert’s service life. Pipes can fracture, corrode, rotate, experience joint pullout, and potentially undergo ... -
Performance of Trenchless Rehabilitations for Culvert, Sewer, and Maintenance Hole Structures
Deterioration and rehabilitation impacts on buried infrastructure were explored using experimental methods. Deterioration studies included the effects of erosion voids (in the immediate backfill) on steel and reinforced ... -
A Phenomenological Model for the Planimetric Evolution of Meandering Rivers and Related Database
This work concerns the planimetric evolution of free meandering rivers, whose associated riverbank erosion and channel changes notoriously pose a hazard to infrastructure within their vicinity as well as affect the health ... -
Physical and numerical modeling of landslide-generated wave runup on steep slopes
Landslides generate waves when they fall into water, and these waves can be major hazards where they interact with coastlines and runup slopes on land. In this thesis, physical and numerical models of landslide-generated ... -
A Physical Investigation of the Flow Structure and Mobility Behaviour of Collisional Granular Landslides
A fundamental understanding of the mechanisms affecting the mobility of granular landslide flow is critical for the management of risk to life and infrastructure below unstable slopes. Modelling methods used in practice ... -
Physical Modelling of Flowslide Mobility
(2008-10-21)Static liquefaction is a sudden decrease of soil shear strength due to the rapid development of pore pressures generated during the collapse of loose, saturated soil deposits. If this type of failure occurs in sloping ... -
Physical modelling of landslides in loose granular soils
(2014-04-29)The catastrophic consequences associated with landslides necessitate predictions of these hazards to be made with as much certainty as possible. However, the often complex nature of these events make predictions highly ... -
Physical Modelling of Retrogressive Landslides In Sensitive Clay
Sensitive clay landslides represent a significant geohazard in Eastern Canada and Scandinavia, often exhibiting complex lateral spreading or flow-like retrogressive behavior. The upslope extent of this hazard is represented ... -
Physical Modelling of Tailings Dam Breach
Tailings dams are constructed in stages, exhibit sediment deposits located in the reservoir upstream of the dam crest (beaches) generated from slurry deposition, and are commonly designed with shallower upstream slopes in ... -
Physical Modelling of the Mobility of Dry Granular Landslides
(2013-09-25)In geotechnical engineering, granular flows are often studied as a means to further the understanding of the mechanisms that drive landslide motion. High quality experimental data is essential in providing evidence for the ... -
Physical Performance of Geomembranes Used in Heap Leach Pad Applications
(2013-02-01)Geomembranes (GMB) are normally used as part of the liner system in heap leach pads. There is a need to quantify tensile strains in the geomembrane that could affect short-term puncture and long-term performance of the ... -
Physical response of composite geomembrane / geosynthetic clay liners under simulated landfill conditions
(2008-09-05)The physical response of composite landfill liners consisting of a geomembrane on top of a geosynthetic clay liner (GCL) are examined under simulated landfill conditions. The deformation and strains of a 1.5-mm-thick ... -
Physical Testing and Finite Element Analysis of a Corrugated High-Density Polyethylene Stormwater Arch Under Deep Burial
The performance of a corrugated, high-density polyethylene stormwater retention arch subjected to deep burial conditions was investigated. Current design methods are based on evaluation of performance under both shallow ... -
Post-Fire Assessment of Unbonded Post-Tensioned Concrete Slabs: Strand Deterioration and Prestress Loss
(2007-12-21)Unbonded post-tensioned concrete slabs have been widely used in Canada and the United States since the 1960s, as they allow increased span-to-depth ratios and excellent control of deflections compared to non-prestressed ... -
The presence and transport of human enteric viruses in fractured bedrock aquifers
(2010-11-11)Both onsite septic disposal systems and private drinking water wells are commonly utilized in rural areas of Canada. The coexistence of septic systems and drinking water wells has the potential to greatly impact the quality ... -
Probabilistic Analysis of Unreinforced and Reinforced Soil Slopes Using the Random Finite Element Method
The focus of this thesis is probabilistic analysis of unreinforced and reinforced soil slopes using the random finite element method (RFEM). RFEM combines the finite element method (FEM) with soil properties that are ...
