2. 1. Geo-environmental considerations in transport infrastructure planning

   Author : Caroline Karlsson; Bo Olofsson; Ulla Mörtberg; Joanne Robison Fernlund; João Manuel Coutinho Rodrigues; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Roads; Railways; Geology; GIS; Decision support; Modelling; Land and Water Resources Engineering; Mark- och vattenteknik;

   Abstract : Transport infrastructure constitutes one of the key factors to a country’s economic growth. Investment in new transport infrastructure might cause potential environmental impacts, and if a project has several alternative corridors open for suggestion then each alternative corridor will have a different impact on the environment.

4. 2. Geoelectrical imaging for interpretation of geological conditions affecting quarry operations

   Author : Mimmi K. Magnusson; Joanne Fernlund; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical resistivity imaging; Rock-mass quality; Aggregate production; Geophysical methods; Induced polarization; Normalized induced polarization; Environmental engineering; Miljöteknik;

   Abstract : Determination of the subsurface geology is very important for the rock quarry industry. This is primarily done by drilling and mapping of the surface geology. However in Sweden the bedrock is often completely covered by Quaternary sediments making the prediction of subsurface geology quite difficult. READ MORE

5. 3. Bonded Particle Model for Jointed Rock Mass

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

   Abstract : 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. READ MORE

6. 4. Physical characterization of coarse clasts with 3D image-analysis method : development, evaluation and application

   Author : Solomon Tafesse; Joanne Fernlund; Mark Johnson; KTH; []
   Keywords : 3D image analysis; Particle angularity; Sieve analysis; Particle form; Gravel analysis; Repeatability; Lithological distribution;

   Abstract : This thesis presents a novel three dimensional (3D) image-analysis method for characterizing the physical characteristics of coarse particles in the field, and introduces new methodology for the total analysis of glacial till samples.The novel image analysis method, called the GID method, is capable of determining the size, shape and surface texture of each individual clast analysed.

7. 5. Physical properties of coarse particles in till coupled to bedrock composition based on new 3D image analysis method

   Author : Solomon Tafesse; Joanne Fernlund; Tore Påsse; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Three-dimensional shape; Grain size; Till lithology; Natural aggregate; Till provenance; Magnetic susceptibility of rock; Physical property of till; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur; Geoengineering; Geoteknik;

   Abstract : The physical properties of the coarse fraction of the till (0.4 to 20 cm) and the surface boulders have been studied at two different sites in Sweden. READ MORE
