  1. 21. Geotechnical Aspects of Buildings on Expansive Soils in Kibaha, Tanzania

    Författare :Charles Lucian; Staffan Hintze; Sven Knutsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Expansive soils; soil properties; potential swell; smectite montmorillonite ; multivariate statistics; geo-statistics; spatial variability; lightweight structures; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur;

    Sammanfattning :  The focus of this study is on potential damages to buildings resulting from expansive soils in Tanzania, particularly clay soils in Kibaha. For the fact that most of the affected structures are founded on expansive soils, a clear understanding of the behaviour of soils and their interaction with structures has been of interest to the study in order to evaluate properly the source of the problem.

  3. 22. Embankments founded on sulphide clay : - some aspects related to ground improvement by vertical drains

    Författare :Rasmus Müller; Stefan Larsson; Göran Sällfors; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; geotechnical engineering; embankments; vertical drains; sulphide clay; Earth sciences; Geovetenskap;

    Sammanfattning : In this thesis, some aspects concerning building embankments founded on sulphide clay are studied, with special reference to ground improvement by preloading in combination with prefabricated vertical drains (PVD’s). The main purpose of the research was to increase empirical knowledge of the mechanical behaviour of sulphide clays subjected to embankment loadings and of the interaction between vertical drains and sulphide clays.

  5. 24. Risk Management in Tunneling Projects : Estimation and Planning

    Författare :Mohammad Mohammadi; Johan Spross; Fredrik Johansson; Stefan Larsson; Anna Kadefors; Amund Bruland; KTH; []
    Nyckelord :Cost overrun; Transport infrastructure projects; Time and cost estimation; Probabilistic approaches; Tunneling; Soil and Rock Mechanics; Jord- och bergmekanik;

    Sammanfattning : Cost overruns and schedule delays are frequently observed occurrences in the construction of transport infrastructure projects. Such phenomena lead to the mismanagement of significant amounts of both public and private resources. LÄS MER

  7. 25. 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
