  3. 2. On the temporal evolution of earth pressures in deep excavations in soft clay

    Författare :Johannes Tornborg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; field monitoring; heave; numerical modelling; earth pressures; soft natural clays; deep excavations;

    Sammanfattning : Urbanisation and sustainable development of cities drives the need to increasingly utilise underground space. Consequently, there is more demand for deeper and larger excavations in urban areas, pushing the limits of current engineering experience. LÄS MER

  4. 3. Probabilistic Stability Analysis of Underground Mine Excavations

    Författare :Musa Adebayo Idris; Tarcísio Celestino; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

    Sammanfattning : The creation of underground mine excavation disturbs the original state of the rock mass surrounding the excavation which often leads to instability of the excavation. This poses a threat to the safety of personnel and equipment in and around such excavations. LÄS MER

  5. 4. Animal husbandry in the Viking Age town of Birka and its hinterland : excavations in the black earth 1990-95

    Författare :Bengt Wigh; Anne Karin Hufthammer; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; animal husbandry; domestication; Viking Age; Birka; cattle; pig; sheep; horse; dog; cat; fur trade; Boskapsskötsel; Kreaturshandel; Uppland; Birka; vikingatiden; Osteologi; historisk osteologi; Historical Osteology;

    Sammanfattning : The Birka Excavations 1990-95 provided a unique opportunity to excavate a Swedish Viking Age town stratigraphically, allowing the finds - including extensive and well-preserved faunal remains - to be dated accurately. This in turn has given the opportunity to study the nature and development of Viking Age animal husbandry in a new, closer perspective. LÄS MER

  7. 5. Sigtuna : Staden, kyrkorna och den kyrkliga organisationen

    Författare :Jonas Ros; Reidar Bertelsen; Uppsala universitet; []

    Sammanfattning : This dissertation focuses especially on the late Viking period and the early Middle Ages. Special emphasis is laid on the town of Sigtuna and the three provinces of Tiundaland, Attundaland and Fjädrundaland (the territory now known as Uppland). Excavations in Sigtuna, including my own, were the beginning of the study. LÄS MER
