Parallel-to-Grain Withdrawal Resistance of Structural Self-Tapping Screws in Canadian Timber
This thesis investigates the withdrawal capacity of self-tapping screws (STS) inserted parallel-to-grain. An experimental study was conducted with 100 screws tested in total. The experimental program includes two main test ... -
Parameter Estimation and Well Installation Optimization for Contaminant Plume Delineation
Groundwater contamination by dense non-aqueous phase liquids (DNAPLs) continues to be a significant environmental problem. DNAPL site characterization forms the basis of DNAPL site remediation success and requires attention. ... -
Passive and Naturalized Landfill Leachate Treatment Systems for Source Water Protection
(2011-10-03)Landfill leachate production is an unavoidable by-product of landfilling solid waste. Mitigation of the adverse environmental impacts of landfill leachate is required at all active and closed landfill sites. Since leachate ... -
Pedestrian-Induced Bridge Response: Using a modal response model to predict the vibrations of a bridge when subjected to periodic pedestrian loads
(2010-05-03)The availability and use of new materials and construction techniques are allowing bridges to be built that are longer and more slender to those that have been constructed in the past. This can cause bridges to have lower ... -
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 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 ... -
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 Slopes and Reinforced Footings Using the Random Finite Element Method
The focus of this thesis was on probabilistic analysis of unreinforced cohesive soil slopes and geosynthetic reinforced and unreinforced footings over cohesive foundations. Two open-source random finite element method ... -
Processes Governing Rapid Recharge Events in a Shallow Fractured Rock Aquifer Having Minimal Overburden Cover
(2013-10-16)The goal of this work is to investigate the influence of overburden cover on controlling recharge to a bedrock aquifer, specifically focusing on rapid recharge events. Rapid recharge events have been observed in a fractured ...
