8th Rock Mechanics and Tunnelling Day
At the end of June 2023, the 8th Rock Mechanics and Tunnelling Day took place at the WBI Center in Weinheim, Germany. This year, the very well-attended event focused on approval procedures and contractual design, traffic tunnel construction, as well as sustainability and life cycle assessment in tunnel construction. It is organized annually by WBI GmbH, sponsored by the German Railway (DB Netz AG) and supported by the German Engineering Association (Arbeitskreis Bautechnik of the Württembergische Ingenieurverein).
Walter Wittke Prize 2023
The Walter Wittke Prize 2023 was awarded to Yota Togashi PhD, PEJp, Assistant Professor at the Graduate School of Science and Engineering, Saitama University, Japan. He received the prize for his dedication to research on anisotropic joint rock masses and the valuable results of his work – especially for the determination of five elastic constants for transversely isotropic rock mass with the aid of only one triaxial test and providing the evidence that uniaxial compressive strength, deformability and anisotropy of Tuff depend on the water content.
