  2. 1. Fracture mechanics studies of non-yielding materials like concrete : modelling of tensile fracture and applied strength analyses

    Author : Per-Johan Gustafsson; Institutioner vid LTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cracking; corners; test-specimens; strength; tension; fracture mechanics; strain localization; size-effect; flexural strength; LEFM; fictitious crack model; Weibull; FEM; pipes; shear strength; concrete; diagonal tension;

    Abstract : Fracture mechanics studies of non-yielding materials are presented. The studies are based on theoretical models for the macroscopical mechanical behaviour of materials during tensile stress induced fracture. A number of applied numercal analysis are indicated. READ MORE

  5. 3. Strength Criteria on Grouting Agents for Hard Rock- Laboratory studies performed on gelling liquid and cementitious grout

    Author : Magnus Axelsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; laboratory study; colloidal silica; rheology; shear strength; Grout; erosion; strength; cement; yield stress; silica sol;

    Abstract : Grouting is usually successful in excavations at moderate depths and groundwater inflow. At great depths, in post-grouting or in rock with a large inflow of water, grouting is more problematic due to the forces from groundwater. READ MORE

  6. 4. Analytical and numerical approaches to estimate peak shear strength of rock joints

    Author : Francisco Ríos Bayona; Stefan Larsson; Fredrik Johansson; Diego Mas Ivars; José Muralha; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rock joint; Shear strength; Failure criterion; Numerical shear tests; Bergsprickor; Skjuvhållfasthet; Brottkriterium; Numeriska skjuvförsök; Byggvetenskap; Civil and Architectural Engineering;

    Abstract : In Sweden, there exists a large number of dams. Many of them are founded on rock masses normally affected by the presence of sub-horizontal rock fractures, which makes sliding along rock joints under the dam foundation one of the most critical failure mechanism. READ MORE

  7. 5. Effects of deep excavations in soft clay on the immediate sourroundings-Analysis of the possibility to predict deformations and reactions against the retaining system

    Author : Anders Kullingsjö; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MIT-S1; Sheet pile wall; Soil-structure interaction; Strain; Stress; Ground surface settlement; Finite element method; Case history; Shear test; Shear strength; Pore pressure; Analysis; Constitutive models; Plane strain; Elastoplasticity; Laboratory tests; Factor of safety; Stiffness; e-ADP; Earth pressure; Anisotropy; Soft Clay; Deep excavation; Retaining wall; Shear stress; Deformation;

    Abstract : When excavating in an urban environment, the evaluation of the magnitude and distribution of ground movements is an important part of the design process, since excessive movements can damage adjacent buildings and utilities. In order to minimize movement of the surrounding soil, a retaining wall support system is used for deep excavations to provide lateral support. READ MORE
