Dr. Tjung specializes in soil mechanics, geotechnical engineering, foundation engineering, earthquake engineering, and computational geomechanics. He has experience on both domestic and international projects including design of new high-rise structures, deep excavations, slope stabilization, retaining walls, failure analysis of dams and slope, and retrofitting of existing structures.
In his projects, Dr. Tjung has incorporated advanced numerical modeling through powerful tools that allowed to accurately analyze complex geotechnical problems. Additionally, he also has experience in data analysis and sustainable design.
Dr. Tjung's experience includes planning and management of geotechnical ground investigations, and design of engineering systems, including deep excavation support, slope stabilization measures, structural foundations, and retaining walls. He has extensive experience performing foundation assessments, evaluation of dams and levees, planning and management of monitoring data, liquefaction assessment, conservation of historic structures, and liaising with office staff, contractors on site, and project management.
Dr. Tjung's has extensive experience modeling large deformation problems in geomechanics using the Material Point Method. With this method, he successfully simulated sand production behavior in an oil rig, 2D and 3D flow of dry sand in laboratory flume experiment, and 3D historical debris flow. Dr. Tjung also initiated the use of the Material Point Method for earthquake applications including a back-analysis study of a liquefaction-induced dam failure. He has in-depth knowledge and experienced with advanced constitutive models based on the critical state understanding for cohesive and dilative behavior of rocks.
At the University of California, Berkeley, Dr. Tjung served as a Graduate Student Researcher (or Research Assistant) and was the Graduate Student Instructor (or Teaching Assistant) for six graduate and undergraduate courses in soil mechanics, geotechnical earthquake engineering, geotechnical ground investigation and laboratory testing, numerical modeling in geotechnical engineering, and numerical analysis. He also held positions in the Graduate Assembly as a delegate of the Civil and Environmental Engineering Department and was one of the founding members of the GeoEngineering Graduate Student Association at U.C. Berkeley, where he organized the Geotechnical Engineering Annual Research Symposium for the university.
Currenly, Dr. Tjung also serves as a lecturer in Smart Construction and Civil Engineering Department of Calvin Institute of Technology in Jakarta, Indonesia. He is teaching undergraduate courses including foundation engineering, statics and mechanics of materials, and numerical analysis.
