  4. 22. Peak Shear Strength of Rock Joints – Towards a Methodology for Prediction Based on Field Data

    Author : Francisco Ríos Bayona; Fredrik Johansson; Diego Mas Ivars; Stefan Larsson; José Muralha; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rock joints; peak shear strength; DEM; matedness; aperture; Bergssprickor; skjuvhållfasthet; DEM; sprickans passning; sprickvidd; Jord- och bergmekanik; Soil and Rock Mechanics;

    Abstract : The rock joint shear strength at field scale is an important design parameter and remains a challenge for rock mechanics engineers. In Sweden, there exist a large number of concrete dams that are founded on rock masses which in many cases contain sub-horizontal rock joints. READ MORE

  5. 23. Free mica in crushed rock aggregates

    Author : Eva Johansson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geoteknik; Soil Mechanics;

    Abstract : Free mica particles in crushed rock aggregates for constructional purposes affect the quality of the end product. It is also known that mica-bearing rocks may cause damages of the road constructions, especially in regions with a temperate climate. The negative influence arises in both bounded and unbounded layers. READ MORE

  6. 24. Modeling aspects of reliability-based design of lined rock caverns

    Author : Davi Rodrigues Damasceno; Fredrik Johansson; Johan Spross; Rafael Jimenez; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lined rock cavern; reliability-based design; analytical modeling; finite element modeling; underground gas storage; Inklädda bergrum; tillförlitlighetsbaserad design; analytisk modellering; finita elementmodellering; underjordisk gaslagring; Soil and Rock Mechanics; Jord- och bergmekanik;

    Abstract : The storage of large quantities of hydrogen gas in underground lined rock caverns (LRCs) could contribute to an efficient supply of fossil-free energy. The consequences of failure of such storage can be catastrophic, so representative predictive models and a small probability of failure are needed for the LRC design. READ MORE

  7. 25. On the mechanical behavior of granite: Constitutive modeling and application to percussive drilling

    Author : Mahdi Saadati; Per-Lennart Larsson; Gioacchino Viggiani; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The mechanical behavior and fragmentation response of rock materials is investigated in this work. In particular, Bohus granite is selected with application to percussive drilling. READ MORE
