  1. 1. Mathematical modelling of jointed rock masses

    Författare :Thomas Olofsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Construction Engineering and Management; Byggproduktion; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : In this thesis, a theoretical model of the mechanical behaviour of jointed rock masses is developed. An equivalent material approach is used to formulate the constitutive equations, where the structural components, intact rock and joints are assigned continuous material properties. LÄS MER

  4. 3. Bonded Particle Model for Jointed Rock Mass

    Författare :Diego Mas Ivars; Joanne MR Fernlund; John Harrison; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bonded particle model; Smooth-joint contact model; Discrete fracture network; Synthetic rock mass; Jointed rock mass; Geoengineering; Geoteknik;

    Sammanfattning : Jointed rock masses are formed of intact rock and joints. There-fore, proper characterization of rock mass behavior has to consid-er the combined behavior of the intact rock blocks and that of the joints. This thesis presents the theoretical background of the Synthetic Rock Mass (SRM) modeling technique along with example applica-tions. LÄS MER
