Background

About Douglas Tun

Douglas Tun is a Geotechnical/Tunnel Engineer who has completed his PhD in soil mechanics, two/three-dimensional numerical modelling for slope stability problems using Limit State, Finite Difference, Finite Element, and Distinct Element Method, data analysis, ground modelling and artificial intelligence. He is a Chartered and National Registered Professional Engineer with six years of small to major transport infrastructure, mining and energy projects experience in Australia, New Zealand, and Myanmar, and four years of research experience. He has been part of different project stages, from the geotechnical investigation, tender design, detailed design, construction phase support and forensic analysis as a designer, design coordinator, project manager, site engineer and an independent reviewer.His experiences in providing geotechnical consultancy for large-scale civil infrastructures (e.g, roads, railways, landfill, etc.) includes the geotechnical design for piles, retaining walls, embankments, cuts, caverns, tunnels, and ground improvement, with site supervision experience on the assessment of rail formation works, foundations, Pile Dynamic Analyzer testing and earthwork construction management. He also has experience in detailed numerical modelling for the complex tunnel junction analysis's primary lining and support system, providing technical advice on tunnel space proofing and three-dimensional sequential tunnel/cavern (up to 30m spans) excavation analysis with numerical modelling software.
