Approche empirique à la calibration d’un modèle d’élément finis d’une mine en roche dure sous l’effet d’un comportement viscoplastique

L’exploitation d’une mine souterraine est sujette à d’importantes contraintes: l’espace de travail réduit, la distance parfois très élevé au minerai et le besoin de renforcer ou de supporter le massif rocheux. C’est sur ce dernier point que porte la présente recherche. Le choix d’un support de terrain approprié repose avant tout sur la bonne compréhension des contraintes (forces) naturel agissant sur notre excavation et les propriétés de résistance de la roche.

Comparative Building Life-Cycle Performance of Insulating Concrete Forms (ICF) Vs. Wood-Frame Construction Phase I: Energy Performance

ICF construction is an alternative for wood-frame construction for residential buildings which potentially has higher energy performance compared. However, this potential advantage has to be measured and compared. This study compares the energy performance of residential buildings constructed with Insulating Concrete Forms (ICF) to those of conventional wood frame buildings in four cities in three different climate zones.

Green Roofs as a Stormwater Management Tool

The intern will undertake a project which analyses several drainage structures of an experimental green roof while developing a numerical model to mimic the experimentally obtained results. In addition, the intern will also be involved in working on an Integrated Stormwater Management Plan, and low impact development methods. The partner organization will benefit by having a more effective green roof drainage design developed as well as a numerical model created to simulate the design changes.

Design and Analysis of Disaster Warning and Evacuation Systems Using the Network Modelling Approach

Canada’s West coast is prone to tsunamis induced from local megathrust earthquakes that can be generated from the Cascadia Subduction Zone (CSZ). The main objective of this research is to study, analyze and simulate the current detection, notification and response systems for an earthquake and resulting tsunami and develop a comprehensive solution using the network modelling approach to mitigate the impact of future disasters. We will use the results and inferences derived from a tornado mitigation analysis to conduct this research.

An assessment of agricultural stream designs used in maintenance operations in Quebec

In agricultural watersheds, many meandering rivers were straightened and several rectilinear ditches were added to the drainage network in order to evacuate water as quickly as possible in the spring to improve farm productivity. The design of these modified channels was not based on natural river dynamic concepts, which include both discharge capacity and sediment transport, and thus need to be maintained frequently as they tend to adjust by eroding their banks and returning to a sinuous pattern.

Caractérisation des propriétés thermomécaniques (TM) d’enrobésspéciaux incorporant des matériaux recyclés provenant de lasidérurgie en vue de leur optimisation

Dans la perspective de préserver les ressources naturelles non renouvelables et de contribuer concrètement à un développement durable, l’entreprise Bauval travaille assidument à la valorisation de résidus industriels, les scories d’aciérie, comme source de granulat dans la production d’enrobés spéciaux ultra-performants. Quatre (4) enrobés à chaud spéciaux de hautes technologies incorporant des scories sont actuellement disponibles : la famille des enrobés Hi Tech.

Model for implementing and continuously improving the automated change management process for construction mega projects

Current communication means such as; Spreadsheet, the internet and Emails are not good enough when a change happens in a Billion $ oil and gas project where hundreds of technicians, engineers, managers, contractors from various disciplines in different locations are involved. The solution is an automated workflow process. Simply put, workflow is the step-by-step procedure taken to complete a job. An automated workflow is the one in which unnecessary time consuming human tasks is eliminated or changed as an automated machine-based task.

A New Generation of Destratification Systems for Large Building Spaces

Thermal stratification is known as “the single biggest waste of energy in buildings today” during heating seasons in large building spaces, where hot air is trapped in the upper section whereas working zones are maintained colder in the lower causing excessive energy losses through ceilings and thermal comfort problems.

Modelling pollutant removal processes for an underground detention chamber system

This project will determine if underground detention systems provide an equivalent level of service for stormwater treatment as stormwater management ponds. This will be achieved through water quality measurements collected from a StormTrap system and through the development of a pollutant-transfer model. The intern will work with both the Toronto Region Conservation Authority and Con Cast Pipe.

Optimal Winter Road Maintenance (WRM) Operations

The proposed research aims to find the optimal application rates of liquid chemicals which are applied to a road surface before and during a snow storm. These chemicals are used to accelerate the melting of snow and ice. The effects of various factors such as traffic, pavement temperature and other environmental factors on the performance of these chemicals will also be investigated. In addition, alternative types of machinery currently used to distribute solid chemicals on the roadways will be compared to examine their effectiveness.
