  1. 1. A comparison of 2D and 3D resistivity surveys for 3D inversion imaging

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Julia Cavell; [2022]
    Nyckelord :;

    Sammanfattning : Following study focuses on electrical resistivity surveying and how it can be used as an exploration method to increase knowledge of subsurface structures. Future scenarios with increasing population and rapid urbani-zation, put high demands on reliable infrastructure; safe foundations, un-derground structures, environmental safety and access to resources.

  4. 3. Kombinerad förundersökning för tunnlar med resistivitet och refraktionsseismik i urban undervattensmiljö

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)

    Författare :Elisabeth Lindvall; Erik Warberg Larsson; [2016]
    Nyckelord :Geophysics; underground; structures; tunneling; construction; urban; TRUST; seismic; resistivity; underwater; survey; geofysik; resistivitet; seismik; undervatten; undersökning; Technology and Engineering;

    Sammanfattning : Due to expanding cities and increasing population infrastructure needs to expand in a safe and sustainable way with little effect on the environment and economy. Years of urbanization doesn’t make it easy, no free spaces are available and culture marked buildings are protected. The only alternative left is to construct in layers. LÄS MER
