Development of reliability-based design for rock engineering

与世界其他地方一样，加拿大的岩土工程设计正在经历一场根本性的变革，正在引入设计规范和标准，这些规范和标准实施了卓越的基于可靠性的设计(RBD)程序，而不是传统的规定或基于工作应力的方法。不幸的是，目前的岩石工程设计程序主要依赖于经验和特别方法的组合，不符合RBD原则。为了安全和经济，迫切需要纠正这一点，本项目的研究旨在做到这一点。*该提案涵盖了支持岩石工程RBD基本发展所必需的三个至关重要的研究主题：1)了解岩石工程中的设计情况；2)处理有限的数据；以及3)发展观测方法。短期目标是发展岩石工程中RBD的基础知识，并提供高质量的HQP培训。更长期的目标是为加拿大和全世界岩石工程设计标准的发展做出重大贡献。预计研究成果将大大推动RBD在岩石工程中的应用，并将成为未来几年进一步重要研究的基础。鉴于迫切需要开发支持现有RBD岩土工程设计规范的知识库，这项研究的影响预计将非常高。研究成果将直接和立即应用于加拿大和世界各地的土木工程和采矿工程部门。将尽最大努力，以最适当的方式，尽可能迅速和广泛地传播研究结果。这将包括对主要国际会议的贡献，发表期刊论文，以及在为执业工程师举办的研讨会上展示结果。*研究将由7名博士生和4名硕士学生共同进行，并将在适当的情况下涉及产业合作。预算全部用于HQP的培训。所有参加研究计划的学生都将接受全方位研究活动的培训，并使用行业标准和新兴的先进工具和技术，特别是在数据分析和数值建模领域。预计参与该计划的学生将在土木工程或采矿工程领域获得岩土工程行业的就业机会，因此将提供培训，帮助他们为此做好准备。拟议的研究计划涉及与业界在许多领域的合作(例如，确定当前的设计实践，设计观察性方法)，学生将全面参与其中，从而获得与潜在雇主的大量接触。

Geotechnical engineering design in Canada, as elsewhere in the world, is undergoing a fundamental change to customary practice in that design codes and standards are being introduced which implement the superior reliability based design (RBD) procedures rather than the traditional prescriptive or working stress based methods. Unfortunately, current rock engineering design procedures rely on a combination of largely empirical and ad hoc approaches that do not comply with RBD principles. There is an urgent need – for the sake of both safety and economy – to rectify this, and the research in this program aims to do so.******The proposal covers three critically important research themes that are necessary to support the fundamental development of RBD for rock engineering: 1) Understanding the design situation in rock engineering; 2) Coping with limited data; and 3) Development of observational approaches. The short-term objectives are to develop the fundamental knowledge base of RBD in rock engineering, and provide high quality HQP training. The longer-term objective is to significantly contribute to the development of rock engineering design standards in Canada and worldwide. It is expected that the research results will significantly advance RBD in rock engineering, and will form the basis of further important research in the years ahead.******The impact of this research is expected to be very high, given the urgent need to develop the knowledge base to support existing RBD geotechnical engineering design codes. The research results will have direct and immediate application to the civil and mining engineering sectors in Canada and worldwide. Great effort will be made to disseminate the results of the research as quickly and widely as possible, using the most appropriate means. This will include contributions to major international conferences, publication of journal papers, and presentation of the results at workshops for practising engineers.******The research will be undertaken by a combination of 7 Doctoral students and 4 Masters students, and will involve industrial collaboration where appropriate. The budget is, in its entirety, devoted to training of HQP. All students in the research program will be trained in the full range of research activities, and the use of industry standard and emerging advanced tools and techniques, particularly in the field of data analysis and numerical modelling. It is expected that the students involved in the program will obtain employment in the geotechnical engineering industry, either in the civil or mining engineering fields, and so training will be given that helps prepare them for this. The proposed research program involves collaboration with industry in many areas (e.g. identifying current design practices, design of observational approaches), and the students will be fully involved in this and thus gain significant exposure to the potential employers.**
