Reliability-based design in rock engineering

这项提议是为了支持创新的世界领先的研究，这些研究将为岩石工程开发迫切需要的基于可靠性的设计(RBD)技术，特别是在土木工程、岩土工程和采矿方面。长期的愿景是开发新的方法和技术，使RBD能够自信地应用于岩石工程设计，从而提高它们的安全性和效率。这项研究将提供出色的HQP培训，并对加拿大和世界各地岩石工程设计标准的制定做出重大贡献。与世界其他地方一样，加拿大的岩土工程设计正在从根本上改变惯例，因为正在引入设计规范和标准，这些规范和标准实施了优越的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。迫切需要纠正这一点，这也是本项目研究的目的。该建议涵盖了岩石工程中RBD的三个至关重要的研究目标：1)改进完整岩石强度的分析和预测；2)改进地应力的概率表征；3)使主观定性评估的作用合理化，以适应RBD。所有这三个目标都满足了岩石工程实践中的迫切需求，预计研究成果都将对岩土工程行业，特别是土木工程和采矿行业产生直接和深远的实际影响。鉴于迫切需要开发知识库来支持现有的RBD岩土工程设计规范，这项研究的影响将是深远和重大的。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部门。研究结果将以最适当的方式尽可能迅速和广泛地传播。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成果。该研究项目支持博士生和硕士研究生，并将在适当的情况下涉及产业合作。该研究计划的所有学生都将接受使用行业标准和新兴的先进工具和技术的培训，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岩土工程行业就业，并将接受培训，为他们做好准备。由于该项目涉及与行业在许多领域的合作，学生将获得与潜在雇主的大量接触。

This proposal is to support innovative world-leading research that will develop urgently needed reliability-based design (RBD) techniques for rock engineering, particularly in civil engineering geotechnics and mining. The long-term vision is to develop new approaches and techniques that will allow confident application of RBD to rock engineering designs, thereby improving their safety and efficiency. The research will provide excellent HQP training, and significantly contribute to the development of rock engineering design standards in Canada and worldwide. 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 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 to rectify this, which the research in this program aims to do. The proposal covers three critically important research objectives for RBD in rock engineering: 1) improving the analysis and prediction of intact rock strength; 2) improving probabilistic characterization of in situ stress, and; 3) rationalizing the role of subjective qualitative assessments so as to suit RBD. All three objectives address urgent needs in rock engineering practice, and the research outcomes are all expected to have immediate and far reaching practical impact to the geotechnical engineering industry, particularly in civil engineering and mining. The impact of this research will be far-reaching and significant, 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 engineering and mining sectors in Canada and worldwide. The results of the research will be disseminated 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 program supports Doctoral and Masters students, and will involve industrial collaboration where appropriate. All students in the research program will be trained in 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, and training will be given to prepare them for this. As the program involves collaboration with industry in many areas, students will gain significant exposure to potential employers.
