"Rock Mechanics and Rock Engineering in Singapore"
This presentation will include 2 parts: Part I will provide an overview on Singapore’s drive in utilising underground space over the last 3 decades, including the past key projects, and potential future developments, as well as challenges we are facing in underground space development. Part II will present a few key R&D development works undertaken by the Nanyang Centre for Underground Space, Nanyang Technological University, including: a) development of discontinuous deformation analysis (DDA) in the area of coupled DDA/FEM analysis and coupled hydro-geological analysis; b) rockbolt modelling in collaboration with Kajima/Japan where numerical models are developed to study the interface behaviour and laboratory tests are used to verify the numerical simulations; c) grouting model and simulations as well as data mining in grouting design, under joint NTU/SINTEF (Norway) project and NTU/KTH collaborations. New flow models are proposed and 2D and 3D simulations are carried out, and available laboratory test data are used for verification study; d) impact of rock blasting on nearby environment, in which both the structural damage as well as the social/psychological impact are studied.
Dr Zhiye Zhao is an Associate Professor from the School of Civil & Environmental Engineering, Nanyang Technological University (NTU), Singapore, and the Director of the Nanyang Centre for Underground Space, NTU. He is a member of the editorial board of Int. J. of Tunnelling and Underground Space Technology, and currently the President of the Society for Rock Mechanics & Engineering Geology (Singapore). Dr Zhao’s research focus is in the area of numerical modelling in rock mechanics/engineering, including development of the discontinuous deformation analysis (DDA), the rockbolt modelling, the rock cavern response under dynamic/blast loads, the coupled hydro-mechanical modelling and rock grouting simulations. His current research projects include: Structural and social impacts of rock blasting on nearby environment with JTC, Development of a Construction Management and Preliminary Design System for Rock Caverns with Hyundai, TIGHT collaboration program with SINTEF, and rockbolt modelling with Kajima.
