SC2 - Quantitative risk assessment in geotechnical engineering: theory and applications, with emphasis on landslides, geohazards, offshore foundations and dams
 
Instructors: Farrokh Nadim and Suzanne Lacasse
Date: Sunday, September 20
Time: 8:30 am – 5:30 pm
Instruction language: English
Cost: Before August 1st – $420; On/After August 1st  – $470 (Students $250)
 
Society and regulations increasingly require that the hazard and risk associated with engineered activities be quantified. Frameworks for quantifying the risk associated with natural hazards and unsatisfactory performance of constructed facilities aim at answering the following questions:
  • What are the probable dangers? [Danger Identification]
  • What would be the magnitude and frequency of danger? [Hazard Assessment]
  • What are the elements at risk? [Elements at Risk Identification]
  • What might be the degree of damage to the elements at risk? [Vulnerability Assessment]
  • What is the probability of damage? [Risk Estimation]
  • What is the significance of the estimated risk? [Risk Evaluation]
  • What should be done? [Risk Management]
Quantitative Risk Assessment (QRA) involves going through each of the above steps, some of which require probabilistic analysis. QRA is an important tool to account for uncertainties in a design, obtain a reliability safety margin and assist the process of decision-making. The probabilistic approach provides a rational framework for taking into account the uncertainties in an engineering design and evaluating the probability of non-performance or failure.

The short course presents hazard assessment in the context of QRA. The practical methods for doing probabilistic analyses, such as first-order, second-moment (FOSM) approach, first- and second-order reliability methods (FORM and SORM). Monte Carlo simulation techniques and event trees are described. The central part of the course is the application of reliability approaches in geotechnical practice. Examples are provided for, among others, slope instability on land, calibration of safety factor, dams and offshore foundations, including the stability of underwater slopes under earthquake loading.

The short course will focus on several geotechnical aspects of permafrost environment and engineering practices for northern transportation infrastructure. The course will begin with considerations of the ground thermal regime in permafrost regions. This will include discussion of factors controlling temperature and thickness of permafrost, and a range of temperature to be expected in in the ground during the year. Ground ice occurrence and development in permafrost terrain will be considered with special attention to the growth of segregated ice lenses. The importance of the presence and the distribution of ice wedges, especially on hillslopes will be emphasized. Principles and methods for site investigation and design of roads, airstrips, railways and other linear structures built in permafrost environments will also be included in the course. The course will provide basic information required to understand the context and the challenges of building linear infrastructures on permafrost. Basic principles leading to effective site investigation, design and management of linear structures built on permafrost will also be presented and discussed.

SC4 - Workshop on numerical analysis for embankment and rockfill dams verification & validation for better prediction

Date: Sunday, September 20
Time: 8:30 am – 5:30 pm
Instruction language: English
Cost: Before August 1st – $420; On/After August 1st – $470 (Students $250)
 
Several dams designed and built in Canada and elsewhere have shown atypical behavior such as the loss of strength of rockfill at first filling or the long term creep. The workshop will provide an overview of current Canadian and international practice for the stress-strain analysis of embankment and rockfill dams. These developments will be presented by experts with emphasis on verification and validation (V&V) importance for correct predictive modeling. According to the V&V approach applied to dam engineering, the dam behavior during its first filling and its service life is the «reality of interest» (complete full scale physical model) and represents the target of our predictions. V&V approach relies heavily on physical models for the validation part of the process in order to demonstrate how «correct» the mathematical and numerical models are. Expanding on these basic principles, the workshop will examine stress-strain analysis of tailing, embankment and rockfill dams. The analysis procedures will be illustrated through examples and/or case histories with emphasis on constitutive models, site instrumentation, statistical analysis of monitoring data, laboratory characterization, statistical prediction models, «benchmarking» process, coupled and multiphysics modeling, etc. This workshop is held in collaboration with Hydro-Québec.

CANCELLED SC5 - Integration of geoscientific data into a geographic information system: Assessment of vulnerability to permafrost degradation (case study of the Inuit community of Salluit, Northern Québec, Canada)
 
Instructor: Richard Fortier
Date: Sunday, September 20
Time: 8:30 am – 5:30 pm
Instruction language: English
Cost: Before August 1st – $420; On/After August 1st – $470 (Students $250)
This course will be given at Université Laval. Cost includes transportation from the conference to Université Laval
 
Vulnerability to natural hazards is a key geoscientific knowledge in decision-making for land use management and planning. For example, the zonation of vulnerability to landslides allows planners to avoid areas of risk for municipal development. An assessment of vulnerability must consider and integrate all available and relevant geoscientific information of a study area. In this short course, a case study in cold regions land use management and planning will be reviewed. Synthesis layers of vulnerability to permafrost degradation for the Inuit community of Salluit in Northern Québec, Canada, will be assessed through the weighted overlays of thematic layers (slopes, Quaternary deposits, surface runoff water, ice content in permafrost and revealing microforms). The rasterization of these thematic layers, their ranging and rankings, and their weighted overlays will be carried out in a geographic information system (GIS) under ArcGIS 10.1. These synthesis layers can be then used for municipal planning purpose. Each participant will produce his own GIS to assess the vulnerability to permafrost degradation using a computer in a laboratory at Université Laval under the supervision of Dr. Richard Fortier. This short course is an introduction to ArcGIS 10.1.
 
About the instructor:
Dr Richard Fortier is a Physics Engineer specialized in northern regions geophysics and engineering. He has a wide-ranging background in lecturing in geophysics and tutoring undergraduate and graduate students, as well as research supervision. He is very active in permafrost science and cold regions engineering in Northern Quebec. He is a specialist in field logistic in remote location, drilling and sampling of ice-rich permafrost, and in situ measurement methods in geotechnics and near-surface geophysics.
 

 
CANCELLED SC6 - Seismic soil-structure interaction

Instructor: Liam Finn
Date: Sunday, September 20
Time: 8:30 a.m. - 5:30 p.m.
Instruction language: English
Cost: Before August 1st – $420; On/After August 1st – $470 (Students $250)
 
Soil-structure interaction has two main components: an approximate but adequate model of interaction between soil and structure and the selection of appropriate ground motions for analysis. Both aspects are covered in the course.

First an introduction to the new probabilistic ground motions in NBCC 2015 is presented and their impact on structural design and seismic liquefaction is discussed. Then the selection and scaling of candidate ground motions for seismic response analysis of soil sites and structures are explained and the number of ground motions required to guarantee a reliable response is discussed.  This background will also be useful in dealing with NBCC (2015) and the new bridge code.

The role of soil-structure interaction (SSI) in the seismic response of slab foundations, pile foundations, bridges, tall buildings, and deep basement walls will be presented in the context of best current practice.  In order to avoid complicated time consuming nonlinear dynamic analysis, current practice simplifies the computational model by separating the soil from the structure and simulating the interaction  by nonlinear springs, for example, p-y curves for single piles and, in addition, interaction factors for pile groups. Many of the quantitative factors in modern practice are based on old and/or limited research and more recent research has found them to be deficient. For example the interaction factors for pile-soil-pile interaction recommended by AASHTO and FEMA are based on tests on small pile groups and recent research has shown that recommendations for large pile groups are inadequate. In a global sense current practice will be evaluated by analysis of the response of an instrumented bridge in California to strong earthquake shaking and comparing calculated and measured responses. All these issues will be clearly explained and recommendations will be made that improve current methods of handling soil-structure interaction in analysis.
 
About the Instructor:
Dr Finn is a Professor Emeritus at the University of British Columbia.
