GSE: Dr. Jim Oswell, Naviq Consulting Inc. - Several Case Histories of Pipeline Distress Induced by Landslides in South America

Location: Faculty Club, University of Alberta

Time: 11:45am Registration, 12:15pm Lunch, 12:30pm Presentation

Cost: $30 Members, $40 Non-Members, $10 Students

Note change in date and speaker.

Those countries in South America that are mountainous have traditionally experienced much higher rates of pipeline incidents caused by landslides than North America. The terrain and climatic conditions are two important factors that influence the negative interaction between slopes and pipelines.This presentation discusses several case histories in two South American countries where post-incident forensic investigations showed that landslides were the direct cause of the pipeline distress. In one unfortunate case, the loss of containment by the pipeline resulted in over 30 fatalities. The initial approach to the investigations and the subsequent geotechnical monitoring and results will be presented....more>>

GSE/CGS Cross Canada Lecture: Dr. Edward Kavazanjian, Jr., Arizona State University - Pre-Design Geotechnical Evaluation for Closure of the Oil Superfund Site Landfill (11th Ralph B. Peck Lecture)

Location: Faculty Club, University of Alberta

Time: 11:45am Registration, 12:15pm Lunch, 12:30pm Presentation

Cost: $30 Members, $40 Non-Members, $10 Students

The pre-design geotechnical investigation for closure of the Operating Industries, Inc. (OII) landfill significantly advanced the state of the art for solid waste landfill engineering. Rising almost 300 ft above grade with slopes as steep as 1.3H:1V, the “orphan” site was placed in the Superfund program in 1986. The landfill, which accepted primarily municipal solid waste, sits astride California State Highway 60 (the Pomona Freeway) and on top of an active earthquake fault considered capable of a magnitude 6.9 earthquake. Due its location, steep slopes and high seismic exposure, the landfill was deemed a “unique urban hazard” by the EPA. The pre-design geotechnical evaluation for closure of the landfill included in situ testing, large scale laboratory testing of waste in an on-site laboratory, seismic hazard and seismic site response analyses, and static and seismic stability analyses of the waste mass and existing interim soil cover. Two different blue-ribbon panels (one for EPA and one for the potentially responsible parties) composed of eminent geotechnical and landfill engineers provided oversight for the work...more>>

All engineering geologists can recognize obvious, young landslides from their sharp, distinct geomorphic elements (headscarp, lateral margins, toe thrust, hummocky topography). However, we often see isolated elements without the others and are unsure of their exact origin and engineering significance. Recent geologic mapping in mountainous areas of Alaska, California, Colorado, and Utah, supplemented by LiDAR DEMs, has revealed an abundance of young scarps, graben, bulges, and other geomorphic anomalies...more>>

U of A Graduate Student Seminar: James P. McCalpin, Distinguished Jahns Lecturer in Engineering Geology - LiDAR Reveals the Bare Earth: LiDAR Geomorphology and its Applications to Engineering Geology

Location: NREF 2-080, University of Alberta

Time: 3:00pm - 4:00pm

Cost: None

Bare-earth DEMs produced by LiDAR, with grid size of 1 m to 6 m, are an engineering geologist’s dream-come-true. In the field of geologic hazards, the DEMs can be used to analyze: 1-active faults, 2-tsunamis, 3-landslides, 4-debris flows, 5-rockfalls, 6-floods, 7-sinkholes, 8-dams, and 9-coastal change. In the field of geologic mapping, Lidar-based DEMs greatly increase the recognition of surficial and bedrock map units, and the accuracy of geologic contacts drawn.

GSE/CGS Cross Canada Lecture: Bob Cameron, Syncrude Canada Ltd. - Case Studies in Soil Parameter Selections for Clay Foundations

Location: Faculty Club, University of Alberta

Time: 5:15pm Registration, 5:45pm Dinner, 6:15pm Presentation

Cost: $30 Members, $40 Non-Members, $10 Students

The methodology developed over 29 years to pick design shear strength and pore pressure parameters for up to 6 different clays will be presented. Anyone who designs large foundations on clay knows it is often not easy to select soil design parameters. The case studies of failures and successes will show examples of how the same clay can have multiple pore water pressure design parameters depending on the whether loaded, or unloaded, and everything in-between. Field measured deformations and pore water pressures for two dump embankment foundations, two dam foundations, two failed slopes, two retaining walls and a mine pit wall will be discussed. It will be shown that one shear strength estimate and one pore water pressure selection for the same clay within even the same design, is not adequate for many of the case studies. Some of the clays noted have high shear strengths across bedding, but very low sliding shear strengths along bedding and weak planes. Trials and tribulations with peak and residual shear strength laboratory testing, total and effective stress considerations and field pore water pressure data will be discussed and shown to provide some very useful, but often misleading or misinterpreted input parameters, unless properly interrogated. Surprisingly, all the clays to be discussed, that act differently and also differ within themselves under different conditions, are all located in the same area...more>>

Day 1: Estimation of Soil Properties for Foundation Design

Soil property estimation is fundamental to all of geotechnical design. For projects with limited budgets, testing will be more limited, and some properties will have to be estimated using correlations. Significant research has been conducted to assess soil property correlations in a realistic manner, including the uncertainty in each correlation. Course concepts include soil property evaluation strategy, geologic inference in property assessment, comparative evaluation of in-situ tests, relative density assessment, in-situ stress evaluation, soil strength evaluation, and deformability estimation.

Day 2: Geotechnical Uncertainty and Reliability-Based Foundation Design

Reliability-based design (RBD) of foundations is presented as a potentially superior alternative to traditional deterministic design. Course concepts include an overview of the development of geotechnical RBD for foundations in North America, followed by a discussion of basic issues of uncertainty, risk, judgment, and RBD formulation. The uncertainty and variability of design parameters are discussed in detail, including load modeling and geotechnical variability. These factors are then integrated into reliability-based equations for foundation design, with application examples.

Cost: $10 Members, $15 Non-Members, $5 Students

With 48,000 kilometers of track, Canada has one of the longest rail networks in the world. Canadians and the Canadian economy depend on the railway system for the transportation of people and freight. As measured by the Transportation Safety Board of Canada, rail is by far the safest means of ground transportation in Canada (Railway Association of Canada, www.railcan.ca). However, due to the geographic diversity of Canada, climatic extremes, and active geological processes, Canada’s rail infrastructure is exposed to infrequent but potentially dangerous natural (ground) hazards. These ground hazards include landslides, erosion, subsidence, avalanches, and frost, among other hazards. These hazards have the potential to result in track failure or make tracks unsafe at the posted speed, and therefore they pose a risk to the safety and operation of Canada’s railways. Ground hazard incidents represent up to 12% of all engineering-related issues, and due to their high cost-per-accident they account for as much as 25% of the cost of engineering-related losses and track outages...more>>

Ron Foster - February 6, 2013

The staff and management of Mobile Augers and Research and MARL Technologies are greatly saddend by the loss of their co-worker and friend, Ron Foster. Ron was travelling to a jobsite Feb. 6 in a pickup truck with drilling assistant Sean Murphy when they were involved in a head-on collision on highway 881, just south of Conklin, AB. Ron was pronounced dead at the scene, and Sean remains in critical but stable condition in hospital in Edmonton. Ron was both a skilled driller and mechanical wizard, whose expertise in his field was second to none. Ron joined Mobile Augers from Garrity and Baker Drilling in 2002, and he had many years of drilling experience before that. He also spent several years working for Mobile's manufacturing sister company, MARL Technologies, where his mechanical aptitude was greatly appreciated. Ron's talents contributed to the design and manufacture of many of the MARL M Series drills. A favourite of his drill helpers for his willingness to teach and his quirkly sense of humour, Ron was a mentor to many people over the years. He will be missed by everyone in the MARL and Mobile family very much. (Excerpt from Mobile Augers release - click link above for the full obituary).
