Design and Uses of Reinforced Shotcrete in Underground Projects in Canada
The first use of steel fibre reinforced shotcrete (SFRS) in Canada was using the wet-mix process in the support of deteriorated ground in 80 year old railway tunnels in the Fraser Canyon,...
Advances in Dry Shotcrete Technology by Means of Microsilica
During the last decade microsilica has been increasingly used to improve both wet and dry mix shotcrete. In the traditional dry process microsilica is blended in the dry mixture. Since...
Advances in Shotcrete Technology for Support of Underground Openings in Canada
This paper presents a broad overview of the state-of-the-art of shotcrete technology for support of underground openings in Canada. Advances in shotcrete technology such as the introduction...
Tuned Mass Dampers for Towers and Buildings
Tuned mass dampers (TMD's) are used to reduce the response of tall slender structures to resonant wind-induced oscillations. This paper reviews the authors' experience with the design...
Passive Energy Dissipation Systems for Earthquake-Resistant Design
Passive energy dissipation devices, also known as supplemental damping devices, have been proposed as a means by which the earthquake resistance of a building can be substantially enhanced,...
A Comparative Study of Different Steel Fibers in Shotcrete
Two steel fiber reinforced shotcrete (sfrs) test programs have been carried out in eastern Canada using steel fibers which are available in the north American marketplace. The first program...
Application of Shotcrete for Ground Support at Inco Mines
In 1989, shotcrete was first successfully introduced for ground support in production areas at Frood Mine. Until then the only successful application of shotcrete had been in major permanent...
Interim Dry Storage of CANDU Fuel
The Canadian approach to permanent disposal of used CANDU fuel is directed toward its storage in suitable containers emplaced into an underground, stable, plutonic rock formation. Reprocessing...
Groundwater Transport Characteristics of Fracture Zones in a Granite Batholith
Major low-dipping fracture zones are the dominant pathways for the large scale circulation of groundwater through the Lac du Bonnet granite batholith of southeast Manitoba, Canada. The...
WAPPA Modeling of Post-Emplacement Performance of the AECL HLNW Package
Environment Canada (EC) is anticipating, in the near future, a review of the EIS document released by AECL which addresses the performance of their HLNW disposal concept. This paper presents...
Nuclear Fuel Waste Disposal: The Canadian Consultative Approach
Over the past two decades society has demanded more public participation and public input into decision-making by governments. Accordingly, development of the Canadian concept for deep...
Using Co-Management in a Voluntary Hazardous Waste Facility Siting Process
The recent approval for construction and operation of a hazardous waste management facility in Manitoba, Canada is an example of a siting process that is voluntary and that gives the community...
Financing the Canadian Nuclear Fuel Waste Disposal Concept
This paper describes an approach to the financial analysis of the Canadian concept for the disposal of high-level nuclear fuel waste. The work was conducted on behalf of Environment Canada...
Ecological Risk Assessment of Proposed Deep Geologic Disposal of High-Level Nuclear Waste in Canada
Using population dynamic models of moose and brook trout, and assuming topographic, hydrographic and other habitat features typical of the Canadian Shield in Ontario, we have estimated...
Defending the Environmental Standpoint: A Report of the Work of Environment Canada in Assessing the Canadian Nuclear Fuel Waste Disposal Concept
Environment Canada, the Canadian environmental department, is participating as an intervenor in the federal environmental assessment of AECL's nuclear fuel waste disposal concept to ensure...
A Computer Model for Multiplant Hydroelectric System Simulation
An interactive computer model of a multi-plant hydrothermal electric power generating system has been developed that roughly captures the main features of the British Columbia Hydro system....
Optimization of Operations?The Manitoba Hydro Experience
As part of a decision support system, Manitoba Hydro implemented a comprehensive optimization model for operations planning in the mid 1980's (Barritt-Flatt and Cormie 1991). Since that...
Analysis of Operating Criteria: Multiple Lakes at Voyageurs National Park
An overview of lake and river regulation at Voyageurs National Park, which resides on the Minnesota-Ontario border, is given to demonstrate how water policy agreements can work. In 1905...
Developing an Ecosystem Approach for Restoration of the Bay of Quinte
Author describes the ecosystem approach that has been utilized for the restoration of the Bay of Quinte. Brief description of the study area is presented. Various problems such as bacterial...
Reservoir Management and Thermal Power Generation
Thermoelectric power stations on regulated rivers may cause violations in stream temperature standards if the dilution water from the upstream reservoir is not adequate. However, it is...
