Evaluating georisk for infrastructure engineering projects

拟议的研究方案侧重于影响基础设施的地质灾害的风险管理。在加拿大，这包括40,000公里的铁轨，安大略省和卑诗省现有的和拟建的隧道，以及安大略省的采矿基础设施。这项研究的目的是主动评估与这些地质灾害相关的风险，以优化现场调查，进一步确定材料特性特征的最佳实践，并继续引领这些结构稳定性和设计的最先进工程分析的发展。此外，基于风险的办法将有助于优化用于改善稳定/减少风险措施的支出。研究结果将对风险管理产生积极影响，提高公众和工人的安全，最大限度地提高基础设施的运营，并在地质灾害确实影响基础设施的情况下降低费用。 研究计划将包括在多个地点开展工作，涉及铁路基础设施(卑诗省白峡谷；安大略省阿尔戈马中央铁路)、铁路和隧道基础设施(安大略省Heron Bay)和采矿基础设施(安大略省萨德伯里、蒂明斯)。该方案的目标包括量化材料性质的不确定性，开发纳入变异性的行为建模技术，开发统一的多危险分析方法，量化设计可靠性，并根据南非采矿风险管理的最新工作，开发风险-后果方法。审查这些基础设施类型的风险管理建立在该行业各个部分正在取得的进展的基础上。 未来五年将招收的学生包括3名本科生、5名硕士和3名博士生。他们将致力于解决与地质灾害相关的最紧迫的问题，并将发展世界级的技能，包括使用最先进的数值模拟和岩土成像工具。所有项目都涉及与工业和政府研究合作伙伴的直接合作，包括CN Rail、CP、加拿大交通部、Quadra FNX、斯特拉塔、淡水河谷和NRCan。

The proposed research program is focussed on risk management of geohazards affecting infrastructure. This includes, in Canada, 40,000 km of railway tracks, current and proposed tunnels in Ontario and BC, and mining infrastructure in Ontario. The objective of this research is to pro-actively assess the risks associated with these geohazards so as to optimize site investigation, further define best practices for material property characterisation and continue to lead development of state of the art engineering analysis of the stability and design of these structures. In addition, the risk based approach will help to optimize expenditures on stability improvement / risk reduction measures. The outcomes of the research will positively affect risk management, enhancing public and worker safety, maximizing infrastructure operation and reducing expenses when geohazards do affect the infrastructure. The research program will include work on a number of sites involving rail infrastructure (White Canyon, BC; Algoma Central Railway, Ont.), rail and tunnel infrastructure (Heron Bay, Ont.), and mining infrastructure (Sudbury, Timmins, Ontario). The objectives of the program include quantification of material property uncertainty, development of behavioural modelling techniques incorporating variability, development of unified multi-hazard analysis methodology, quantification of design reliability, and development of the risk-consequence approach, based on recent work in South African mining risk management. Examining risk management for these infrastructure types builds on advances being made in individual parts of the industry. Students to be recruited to the research program over the next five years, include 3 undergraduate employees, 5 masters and 3 doctoral students. They will work on the most pressing problems associated with geohazards, and will develop a world class skill set including use of state of the art numerical simulation and geotechnical imaging tools. All projects involve working directly with industrial and government research collaborators, including CN Rail, CP, Transport Canada, Quadra FNX, XStrata, Vale and NRCan.
