Topic An update on the ongoing geotechnical work related to the seismic hazard characterization of Fox Creek
Abstract The recent increase of small to moderate induced seismicity in some of the Canadian unconventional plays is raising concerns...
  on the potential effects that such events can cause to existing structures and to the slopes. Industry and academia are collaborating to define the seismic hazard in some of the most impacted areas. The Fox Creek area, AB, has experienced a number of tremors in the last two years. This presentation provides an update on the ongoing geotechnical work related to the seismic hazard characterization of Fox Creek. After a short introduction on the recent increase of induced seismicity, focus will be given to a) the uncertain soil properties impacting the ground-motion amplification, b) the foundation factors produced to replace those adopted in the current National Building Code (NBCC 2015), c) the seismic vulnerability of natural slopes, and d) soil-structure interaction including pipelines and water retention structures.

Speakers Amy Rentz, Ph.D., Thurber Engineering Ltd.
  Amy Rentz is currently working as a Junior Geotechnical Engineer for Thurber Engineering Ltd. in Calgary. She received her Bachelor of Applied Science degree in Civil Engineering from Queen's University and more recently completed her PhD at Queen's University under the supervision of Dr. Richard Brachman, Dr. Kerry Rowe and Dr. Andy Take. Her research focused on geosynthetic composite liner systems and how they perform when left uncovered after installation. The findings of her work reinforce the importance of following the manufacturer's recommendations and covering these composite liner systems in a timely manner.
Topic Field Performance of Exposed Geosynthetic Composite Liner Systems
Abstract It is common for a geomembrane (GMB) and a geosynthetic clay liner (GCL) to be used in combination as a low hydraulic...
  conductivity composite liner system. These composite liner systems have been widely used as municipal solid waste landfill barriers for the past two decades and are now increasing in popularity as a liner system in mining applications. They have proven to be effective leakage barriers to contaminants when the manufacturers' recommendations for installation and quality control procedures have been followed including timely covering of the composite liner with cover soil. However, it is not uncommon in some jurisdictions in North America and elsewhere for GMB/GCL composite liners to be left exposed to solar energy for weeks, months, even years after installation as the result of operational and/or cost considerations. Leaving these composite liners uncovered and exposed to solar energy has been reported to degrade the effectiveness of the composite barrier system through three different mechanisms, namely geomembrane wrinkling, GCL panel shrinkage, and more recently observed down-slope erosion of bentonite from a GCL.
This presentation will summarize the findings from a large-scale field study, where the objective was to quantify the performance of GMB/GCL composite liner systems (composed of different types of GCLs and black versus white GMBs) in terms of the three degradation mechanisms listed above.

Topic Foundations for the Ice District towers E and A in Edmonton
Abstract This project is part of Edmonton's downtown ICE district development which will be Canada's largest mixed-use sports and...
  entertainment district. The presentation will describe the construction of the foundation piles for the JW Marriot hotel (tower A) and the Stantec tower (tower E) which will be the tallest tower in western Canada with 66 floors. The foundations for the towers consisted of steel reinforced piles with diameters of 1.5m and 1.85m and lengths up to 75m. Construction of the piles occurred inside an 18m deep excavated pit which presented unique challenges in terms of space, heavy lifts and material deliveries. Prior to the installation of the working piles, Oesterberg load tests were performed one of which was tested up to a load of 47MN in order to confirm the design parameters. All the installed piles were tested with Cross-Hole Sonic logging (CSL) to confirm their integrity.

He supervised settlement control of historically significant 17th century buildings that required mitigating measures.
Topic Digging a tunnel in very soft soils underneath a city built on 400 year old wooden piles
Abstract The realization of the metro system in Amsterdam has been a precarious topic for the citizens, going back to the construction...
  of the underground East-West line in the 1970s. Historic buildings were demolished to make room for the new metro line -built using open pit construction- which led to large protests. To prevent further damage to the city and resistance from its people, a tunnel boring machine (TBM) was introduced during planning and design of the new North-South metro line. But how do you prevent damages to 17th century buildings caused by settlements of the wooden piles while a TBM is going underneath? This proved to be one of the main challenges of this alternative way of construction.

Topic Evaluating Liquefaction in Finely Interbedded Sand, Silt and Clay Deposits
Abstract Current liquefaction evaluation procedures have a tendency to over-predict liquefaction effects in finely inter-bedded sand, silt...
  and clay deposits. The nature and extent of this apparent bias are illustrated using case histories, and the potential reasons discussed. Three related research projects are then described.
The performance of the Cark Canal in the 1999 Kocaeli earthquake is re-examined using one-dimensional CPT-based liquefaction vulnerability indices and nonlinear deformation analyses with spatially correlated stochastic models; the results illustrate the importance of spatial variability to field performance and the inherent limitations in 1D LVI methods. The relationship between cyclic strength and cone penetration resistance in low-plasticity fine-grained soils is examined using laboratory testing and simulated cone penetration resistances; the results provide insights on potential biases in existing liquefaction triggering models. An axisymmetric direct cone penetration model is developed for use with the MIT-S1 constitutive model and its capabilities illustrated by simulating penetration resistance in anisotropic clay. Future research needs and recommended practices for evaluating liquefaction effects in finely interbedded sand, silt and clay deposits are discussed.

Speakers Jiechun Wu, M.Sc. Candidate, Department of Civil Engineering, University of Calgary
  Jiechun Wu is currently an M.Sc candidate in the Department of Civil Engineering and a Research Assistant in Gas Hydrate Geomechanics Group at University of Calgary. During his M.Sc study, he specialized in advanced laboratory soil testing on gas hydrate-bearing sediments. He has experience in developing hydrate formation techniques within sediments and determining strength, stiffness and dissociative behaviour of hydrate-bearing sediments based on experimental results.
Topic Geomechanical Behaviour of Hydrate-bearing Fine-grained Sediments
Abstract Gas hydrates are ice-like compounds formed of methane gas and water that are stable under certain temperature and...
  pressure conditions that exist within the sediments on the continental margins of the world's oceans and beneath permafrost areas in Arctic. Gas hydrate has attracted considerable attention due to its potential as a significant future energy source, a drive for global climate change and a trigger for geotechnical hazards, since hydrate dissociation can significantly reduce the strength of sediments if the temperature and pressure conditions are sufficiently altered. The geomechanical properties of hydrate-bearing sediments, and the change in sediment behavior during hydrate dissociation, is heavily dependent on the hydrate morphology within the sediment. In this presentation, the forming technique of hydrate within sediments and advanced triaxial tests on the hydrate-bearing sediments are introduced. The impact of hydrate on the geomechanical behavior of fine-grained soil sediments is analyzed.
