    Författare :Fanny Deckner; Staffan Hintze; Kenneth Viking; Steinar Nordal; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ground vibrations; sheet piles; vibratory driving; vibration transfer process; instrumentation system; field tests; numerical modelling; vibration prediction; markvibrationer; spont; vibrodrivning; vibrationsöverföringsprocessen; instrumenteringssystem; fältförsök; numerisk modellering; vibrationsprognosticering; Civil and Architectural Engineering; Byggvetenskap;

    Sammanfattning : Vibratory driven sheet piles are a cost-effective retaining wall structure, and in coming decades the continued use of this method will be crucial for minimising costs within the construction sector. However, vibratory driven sheet piles are a source of ground vibrations, which may harm structures or induce disturbance. LÄS MER

  3. 2. Ground vibrations due to pile and sheet pile driving : influencing factors, predictions and measurements

    Författare :Fanny Deckner; Staffan Hintze; Kenneth Viking; Sigurdur Erlingsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ground vibration; pile; sheet pile; prediction; markvibrationer; påle; spont; prediktion;

    Sammanfattning : Ground vibrations due to pile driving are part of a complex process. Vibration is generated from the pile driver to the pile. As the pile interacts with the surrounding soil, vibrations are transferred at the pile-soil interface. The vibration propagates through the ground and interacts with structures, both above ground and underground. LÄS MER

  4. 3. Ground Improvement by Dry Deep Mixing Lime-Cement Column Panels as Excavation Support

    Författare :Razvan Ignat; Stefan Larsson; Sadek Baker; Sven Liedberg; Masaki Kitazume; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Many urban areas near the coastal regions of Sweden are characterized by post-glacial clay deposits with very low undrained shear strength and high compressibility. Column type ground improvement by the Deep Mixing, DM, method using a binder mixture of lime and cement is commonly used in areas with poor soil conditions due to its cost-effectiveness, predominantly for settlement reduction and to improve the stability of embankments.
