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，即引入设计规范和标准，实施基于高可靠性的设计（RBD）程序，而不是传统的规范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临时方法的结合，这些方法不符合RBD原则。出于安全和经济的考虑，迫切需要纠正这一点，而本项目的研究旨在做到这一点。******该提案涵盖了三个至关重要的研究主题，这些主题对于支持岩石工程RBD的基础发展是必要的：1)了解岩石工程中的设计情况；2)处理有限的数据；3)发展观测方法。短期目标是建立岩石工程中RBD的基础知识基础，并提供高质量的HQP培训。长期目标是为加拿大和世界范围内岩石工程设计标准的发展做出重大贡献。预计研究成果将显著推进RBD在岩石工程中的应用，并将为今后几年进一步的重要研究奠定基础。******考虑到迫切需要开发知识库来支持现有的RBD岩土工程设计规范，这项研究的影响预计将非常大。研究成果将直接应用于加拿大和世界各地的土木和采矿工程部门。将作出巨大努力，利用最适当的手段，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，期刊论文的出版，以及在实践工程师研讨会上的成果介绍。******这项研究将由7名博士生和4名硕士生共同承担，并在适当的情况下涉及工业合作。预算全部用于HQP的培训。该研究项目的所有学生都将接受全方位的研究活动培训，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或采矿工程领域的岩土工程行业就业，因此将给予培训，帮助他们为此做好准备。拟议的研究计划涉及在许多领域与行业合作（例如确定当前的设计实践，观察方法的设计），学生将充分参与其中，从而获得潜在雇主的重要曝光。**

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.**
