  1. 1. Innovative seismic imaging solutions : From hardrock mineral exploration to quick-clay site characterization

    Författare :Tatiana Pertuz; Alireza Malehmir; Cesare Comina; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Seismic methods; mineral exploration; quick-clays; seismic imaging; seismic characterization; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

    Sammanfattning : Seismic methods are an efficient and powerful tool to explore the subsurface. It principally helps to gain information on the subsurface structure, bedrock topography, and the nature of the host rock. LÄS MER

  3. 2. 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

  4. 3. Soil identification by vibration measurements during soil-rock sounding

    Författare :Editha Ehrmanntraut; Stefan Larsson; Jörgen Johansson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ground vibrations; dynamic penetration testing; frequency; seismic test; vibration velocity; in-situ tests; markvibrationer; dynamiska sonderingsmetoder; frekvens; seismiska försök; vibrationshastighet; in-situ-försök; Jord- och bergmekanik; Soil and Rock Mechanics;

    Sammanfattning : Dynamic penetration tests are frequently used as geotechnical site investigation methods. In Sweden, the main reason to choose a dynamic penetration method is to investigatedepth to bedrock, strength and deformation properties of soil, compaction, or pilingdepth. LÄS MER

  5. 4. Laboratory Seismic Testing of Asphalt Concrete

    Författare :Anders Gudmarsson; Nils Rydén; Björn Birgisson; Hervé Di Bendetto; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Nondestructive laboratory seismic testing to characterize the complex modulus and Poisson’s ratio of asphalt concrete is presented in this thesis. These material properties are directly related to pavement quality and the dynamic Young’s modulus is used in thickness design of pavements. LÄS MER

  7. 5. Recovering Moho parameters using gravimetric and seismic data

    Författare :Majid Abrehdary; Lars E. Sjöberg; Mohammad Bagherbandi; Pavel Novák; KTH; []
    Nyckelord :crust; gravity; mantle; Moho depth; non-isostatic effect; residual isostatic topography; stripping; thermal state; Vening Meinesz-Moritz model; Geodesy and Geoinformatics; Geodesi och geoinformatik;

    Sammanfattning : Isostasy is a key concept in geoscience to interpret the state of mass balance between the Earth’s crust and mantle. There are four well-known isostatic models: the classical models of Airy/Heiskanen (A/H), Pratt/Hayford (P/H), and Vening Meinesz (VM) and the modern model of Vening Meinesz-Moritz (VMM). LÄS MER
