  1. 1. Modelling and simulation of vibratory driven sheet piles - Development of a stop criterion

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Författare :Johannes Jonsson; Anton Andersson; [2021]
    Nyckelord :Vibratory driving; sheet pile; Technology and Engineering;

    Sammanfattning : During excavations, steel sheet piles are often installed through vibratory driving, to establish a retaining wall that resists soil instability and ground water leakage. The method of vibratory driving is that the sheet pile is driven into the soil with a vertical vibratory motion. This is especially effective in soft soils. LÄS MER

  3. 2. Dynamisk finita element-analys av vibrodriven spontplanka

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Geoteknik; Lunds universitet/Institutionen för byggvetenskaper

    Författare :Rasmus Tebäck; [2019]
    Nyckelord :Finita elementmetoden; dynamisk; geoteknik; spont; stödkonstruktioner; Technology and Engineering;

    Sammanfattning : Stödkonstruktioner används när schakter blir för djupa för att vara självbärande eller när slänter inte kan användas av utrymmesskäl. Det finns flera olika lösningar för stödkonstruktioner och en av de vanligast förekommande är stålspont. LÄS MER

  4. 3. Vibration caused by sheet pile driving- effect of driving equipment

    Master-uppsats, KTH/Jord- och bergmekanik

    Författare :Haftom Tesfay Tsegay; [2018]
    Nyckelord :Ground vibration; vibratory driving; sheet pile; eccentric moment; markvibrationer; vibrerade drivning; spont; excentriska moment.;

    Sammanfattning : In many construction works in urban areas vibratory driving is the most widely used technique toinstall sheet piles. But due to vibration-sensitive equipment and structures the amount of inducedground vibration need to be minimized. LÄS MER

  5. 4. Soil Plugging of Open-Ended Piles During Impact Driving in Cohesion-less Soil

    Master-uppsats, KTH/Jord- och bergmekanik

    Författare :Victor Karlowskis; [2014]
    Nyckelord :soil plugging; impact driving; driving resistance; driving records; jordpluggning; slagdrivning; drivmotstånd; pålprotokoll;

    Sammanfattning : During impact driving of open-ended piles through cohesion-less soil the internal soil column may mobilize enough internal shaft resistance to prevent new soil from entering the pile. This phenomena, referred to as soil plugging, changes the driving characteristics of the open-ended pile to that of a closed-ended, full displacement pile. LÄS MER

  7. 5. Pile – Soil Interaction during Vibratory Sheet Pile Driving : a Full Scale Field Study

    Master-uppsats, KTH/Jord- och bergmekanik

    Författare :Claire Guillement; [2013]
    Nyckelord :Ground vibrations; vibratory driving; sheet pile; full-scale field study; soil instrumentation; sheet pile instrumentation.;

    Sammanfattning : Urban construction sites require strict control of their environmental impact, which, for vibratory sheet pile driving, can include damage to nearby structures due to ground vibrations. However, the lack of knowledge concerning the generation of soil vibrations makes the prediction of ground vibration levels difficult. This MSc. LÄS MER
