Dr. Jonny Sjöberg即将出任Itasca国际咨询公司CEO
1 引言
2 Dr. Sjöberg简介
Dr. Sjöberg是瑞典Itasca Consultants AB公司的总经理和主任工程师(Principal),专业为采矿岩石力学,在采矿和土木工程领域的运营、研究和咨询方面有丰富的经验。他拥有露天边坡稳定性领域的博士学位,并曾在地下和露天采矿项目中从事岩石力学、土木工程隧道项目、应力测量和其他各种数值模拟项目。Sjöberg博士也是吕勒奥理工大学(Luleå University of Technology)岩石力学和岩石工程的兼 职教授。在我们过去的公 众 号文章中,有3篇文章直接提到了Dr. Sjöberg:(1) 第2届欧洲岩石力学辩论会(Eurock Debate 2)---数值模拟的方法 论(视频)
在那个视频中,Dr. Sjöberg的演讲题目为《Principles, Capabilities, and Strategies for Choosing Models(选择模型的原则、能力和策略)》,主要讨论了以下问题:(1) 数值模拟模拟什么以及为什么模拟;
(2) 数值模拟的发展趋向;[Challenges in current slope stability analysis methods]
(3) 耦合模拟(HM, THMC)以及颗粒流与力学的耦合;[Analysis of caving and ground deformations in Malmberget using a coupled CAVESIM–FLAC3D model]
(4) 实时模拟和结果解释的机器学习[短期课程: Introduction To Machine Learning In Geomechanics---A Comparison of Classical Numerical Modeling to the New Paradigm of Machine Learning];
(5) 选择数值模型的原则和策略;
(6) Verification, Validation和Calibration之间的区别与联系。
Dr. Sjöberg最被广泛引用的研究工作是他于1996年完成的技术报告《Large Scale Slope Stability In Open Pit Mining - A Review,229p.》,采矿岩石力学数据库的部分矿山案例就起源于他的这个报告。
3 Dr. Sjöberg论文(2018-Present)Dr. Sjöberg的这些论文主要涉及了瑞典和其它欧洲的一些大型露天开采和地下开采项目的研究,包括:Malmberget, Kiirunavaara, Olkiluoto, Forsmark等。
