1. 1. On the Application of Surface Wave Surveys for Seismic Site Response Evaluation

   Författare :Edwin Obando; Teknisk geologi; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Surface wave; MASW; seismic site response; ground motion; seismic transfer functions; shear wave velocity; site amplification; walk-away; near-field effect; dispersion curve.;

   Sammanfattning : In sites where earthquakes occur, the use of surface wave methods represents a convenient and effective procedure for soil characterization. In particular, Multichannel Analysis of Surface Wave (MASW) has become a popular tool in many seismic micro-zoning projects. LÄS MER

3. 2. On the small strain stiffness of some Scandinavian clays and impact on deep excavation

   Författare :Tara Wood; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; soft clay; small strain stiffness; degradation; seismic testing; sample quality;

   Sammanfattning : This thesis presents the results of a comprehensive study on the small strain stiffness of several Swedish clays and its tentative effect on the design of retaining structures. A combination of field measurement techniques, seismic dilatometer and surface seismics, are complemented with bender element testing of the retrieved samples. LÄS MER

4. 3. Three-component digital-based seismic landstreamer : Methodologies for infrastructure planning applications

   Författare :Bojan Brodic; Alireza Malehmir; Christopher Juhlin; André Pugin; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; landstreamer; multicomponent seismic; shear-waves; surface-waves; Geophysics with specialization in Solid Earth Physics; Geofysik med inriktning mot fasta jordens fysik;

   Sammanfattning : To support urban infrastructure planning projects, along with various other near-surface applications, a multicomponent landstreamer was developed. The landstreamer was built with broadband (0-800 Hz), three-component (3C) micro-electro-mechanical system (MEMS) sensors. LÄS MER

5. 4. Surface Wave Testing of Pavements

   Författare :Nils Rydén; Teknisk geologi; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; geographical and geological engineering; Hydrogeologi; teknisk geologi; teknisk geografi; Hydrogeology; inversion; guided waves; road; pavement; Surface waves; non-destructive testing;

   Sammanfattning : A novel approach for surface wave testing of pavements is presented. It is a non-destructive testing (NDT) technique that can be used to obtain the thickness and stiffness properties of the different layers in a pavement. LÄS MER
