Rock Slope Geohazard Assessment and Mitigation to Protect People and Infrastructure

未来十年，由于人口增长和新的天然气、石油和采矿开发，加拿大将在陡峭的地形上建造数十亿美元的新基础设施。居住或工作在陡峭岩石斜坡及相关基础设施附近的人们容易受到地质灾害的影响。该研究方案的长期目标是改进地质灾害评估技术，并在地质灾害评估与设计适当的风险缓解措施之间建立缺失的联系，以减少岩石从陡峭的岩石斜坡上坠落造成的损失。短期目标解决了目前陡岩边坡风险管理中的三个不足。现有的地质灾害评估方法耗时太长，并且可能使从事评估的岩土工程师暴露在不安全的野外工作中。过于简单的几何公式（在当前的建筑规范中）被用来定义安全的建筑区域；这些公式没有考虑岩体质量和基础设施易损性等重要因素。新技术，如斜坡网格已经在加拿大引入，但需要设计方法来指定这些应该如何使用。研究目标是：

Billions of dollars of new infrastructure will be built in steep terrain in Canada over the coming decade due to population growth and new natural gas, oil, and mining developments. People living or working near steep rock slopes and the associated infrastructure are exposed to geohazards. The long-term objectives of the research program are to improve geohazard assessment techniques and to build the missing links between geohazard assessment and the design of appropriate risk mitigation measures to reduce losses associated with rock falling from steep rock slopes. The short-term objectives address three deficiencies in the current risk management for steep rock slopes. Existing geohazard assessment methods can take too long and can expose geotechnical engineers doing the assessment to unsafe fieldwork. Overly simplistic geometric formulae (in current building codes) are used to define areas where it is safe to build; these formulae do not consider important factors such as the rock mass quality and the infrastructure vulnerability. New technologies such as slope meshing have been introduced in Canada but design methods are needed for specifying how these should be used.  The research objectives are to:
