  1. 1. Prediction and experimental validation of dynamic soil-structure interaction of an end-bearing pile foundation in soft clay

    Författare :Freddie Theland; Jean-Marc Battini; Amir Kaynia; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dynamic soil-structure interaction; Pile group; End-bearing piles; Dynamic impedance; Environmental vibration; Experimental validation; Dynamisk jord-struktur-interaktion; Pålgrupp; Spetsbärande pålar; Dynamisk impedans; Omgivningsvibrationer; Experimentell validering; Structural Engineering and Bridges; Bro- och stålbyggnad;

    Sammanfattning : In the built environment, human activities such as railway and road traffic, constructionworks or industrial manufacturing can give rise to ground borne vibrations. Such vibrations become a concern in urban areas as they can cause human discomfort or disruption of vibration sensitive equipment in buildings. LÄS MER
