  2. 16. Quality aspects in direct shear testing of rock joints

    Author : Jörgen Larsson; Fredrik Johansson; Alejano Leandro; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rock joints; geometrical quality assurance; replicas; direct shear testing; normal stiffness; bergssprickor; geometrisk kvalitetssäkring; replikor; skjuvhållfasthetprovning; normalstyvhet.; Jord- och bergmekanik; Soil and Rock Mechanics;

    Abstract : The stability of rock masses is influenced by the occurrence of rock joints. Therefore, the shear strength of rock joints must be considered in dimensioning of underground constructions. READ MORE

  4. 17. Design approaches for grouting of rock fractures; Theory and practice

    Author : Jalaleddin Yaghoobi Rafi; Stefan Larsson; Håkan Stille; Thomas Dalmalm; Lars Ericsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Grouting; Rock mechanics; Jacking; penetration length; Järnvägsgruppen - Infrastruktur; Järnvägsgruppen - Infrastruktur;

    Abstract : Currently, cement base grout is used widely for sealing of the rock fractures in order to decrease the permeability of rock mass. Grouting procedure is one of the main tasks in cycle of rock excavation. In addition, huge amount of grout should be used during dam construction in order to seal the bedding and embankment walls.

    Abstract : The underground is a vast region, which is, too a large extent, unused by man. It has a large potential as a storage facility due to its vastness and availability. This thesis, which consists of eleven papers and reports, deals with nuclear waste repositories in solid rock and with aquifer thermal energy storage systems. READ MORE
