2. 1. Integrated geophysical-geochemical methods for archaeological prospecting

   Author : Kjell Persson; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Geophysics; geophysical; geochemical; prospecting; archaeology; electric; magnetometric; Geofysik; Geophysics; Geofysik;

   Abstract : A great number of field measurements with different methods and instruments were conducted in attempts to develop a method for an optimal combination of various geochemical and geophysical methods in archaeological prospecting. The research presented in this thesis focuses on a study of how different anthropogenic changes in the ground can be detected by geochemical and geophysical mapping and how the results can be presented.

4. 2. Multimethod characterization of a chlorinated solvents contaminated site and geoelectrical monitoring of in-situ bioremediation

   Author : Aristeidis Nivorlis; Teknisk geologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geoelectrical monitoring; induced polarization 1P ; contamination remediation geophysics; Time-lapse inversion; autonomous geophysical monitoring;

   Abstract : Soil contamination is a widespread problem and actions need to be taken in order toprevent damage to the groundwater and the life around the contaminated sites. InSweden more than 80.000 sites are potentially contaminated, therefore there is ademand for accurate and efficient methods for site characterization and soilremediation. READ MORE

5. 3. Remnant echoes of the past : Archaeological geophysical prospection in Sweden

   Author : Andreas Viberg; Kerstin Lidén; Bo Olofsson; Rinita Dalan; Bruce Bevan; Neil Price; Stockholms universitet; []
   Keywords : HUMANIORA; HUMANITIES; Archaeological prospection; geophysical survey; Sweden; Ground-penetrating radar; magnetometry; Slingram; magnetic susceptibility; Neolithic; Migration period; Viking Age; Middle Ages; Öland; Gotland; Sigtuna; Lapland; Archaeological Science; laborativ arkeologi;

   Abstract : The aim of this thesis has been to investigate the benefits, pitfalls and possibilities of using geophysical methods in archaeological projects. This is exemplified by surveys carried out at archaeological sites in different geographical and chronological contexts. READ MORE

6. 4. Monitoring of tailings dams with geophysical methods

   Author : Ganesh Mainali; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och Berganläggningsteknik;

   Abstract : Several dam failure accidents have occurred during the last years and mine tailings dam failures are occurring at relatively high rates. Studies of past earth dam failures show embankment dam problems and failures are often related to internal erosion in one way or another. 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
