  1. 1. High-resolution offshore reflection seismic investigation of the Stockholm Bypass tunnel

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Fengyi Liu; [2017]
    Keywords : infrastructure; tunnel; seismic; reflection; multiple; engineering;

    Abstract : Boat-towed high-frequency, short source and receiver spacing, reflection seismic data, 16 profiles and in total 3884 m long, were acquired in 2008 for the planning of the Stockholm Bypass multilane (3 lanes in each direction in two different tubes) underground motorway tunnel designed to ease the ever increasing car traffic on the city and neighbouring regions. The planned bypass will be about 21 km long of which 18 km will be in the form of bedrock tunnel. READ MORE

  3. 2. Limitations of the Ground Reaction Curve Concept for Shallow Tunnels Under Anisotropic In-situ Stress Conditions

    University essay from KTH/Jord- och bergmekanik

    Author : Diego Lope Álvarez; [2012]
    Keywords : Ground reaction curve; shallow tunnels; isotropic stress conditions; anisotropic stress conditions; analytical solution;

    Abstract : The deep mining industry and civil engineering need to perform rock stability analyses during excavation projects. These analyses are closely related with displacements in tunnel contours. The ground reaction curve is a powerful tool to characterize these displacements that is widely used in the New Austrian Tunneling Method. READ MORE

  4. 3. Stability Analysis of Shallow Tunnel of Norra Länken

    University essay from KTH/Jord- och bergmekanik

    Author : Rana Muhammad Sajid Imran Khan; Kabindra Man Shrestha; [2011]
    Keywords : FEM Calculation; Shallow Tunnel; PLAXIS; Norra Länken;

    Abstract : Shallow Tunneling through highly populated areas of big cities is a challenging task. Almost in all the tunneling projects of shallow tunnel some or the other types of tunneling problems have been encountered and are still being faced. READ MORE

  5. 4. Master thesis in interpretation of controlled-source radiomagnetotelluric data from Hallandsåsen

    University essay from Geofysik

    Author : Martin Hjärtén; [2007]
    Keywords : controlled-source radiomagnetotelluric; radiomagnetotelluric; magnetotelluric;

    Abstract : Controlled Source Tensor Magnetotelluric (CSTMT) ground measurements were executed on the Hallandsåsen horst where a major tunnel is under construction. The instrument system EnviroMT are used for this purpose. READ MORE

  6. 5. Litostratigrafiska studier av en platåformad sand- och grusavlagring i Skuremåla, Blekinge

    University essay from Lunds universitet/Geologiska institutionen

    Author : Fredrik Stenfeldt; [2006]
    Keywords : Skuremåla; litostratigrafi; deglaciation; randfält; strandförskjutning; Baltiska Issjön; Blekinge; lithostratigraphy; subaqueous fan; shoreline displacement; Baltic Ice Lake; Earth and Environmental Sciences;

    Abstract : I Skuremåla, Blekinge har litostratigrafiska studier utförts av en platåformad grus- och sandavlagring. Skuremåla-avlagringen har tidigare beskrivits som ett delta med en överyta på 55 m ö h. Syftet med arbetet är att tolka vad för sorts ”delta” Skuremåla-avlagringen utgör samt depositionsmiljön för sedimenten i fråga. READ MORE
