  1. 1. Mechanical properties of inorganic silt

    Författare :Lennart Börgesson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Sammanfattning : The need for increased knowledge of the properties and behaviour of silty soils has been urgent for many years. This report is an attempt to fulfil this need to same degree. The properties of inorganic silt have been investigated by means of laboratory tests, field tests and load tests. LÄS MER

  3. 2. Stabilization of fine-grained soils in cold environment and exposed to seasonal frost : By-products as hydraulic binders

    Sammanfattning : This doctoral thesis deals with the stabilization of fine-grained soils using by-product originated hydraulic binders. The use of fine-grained soils as subsoil for infrastructure projects is often limited because of the risk for instability. LÄS MER

  4. 3. Modelling of Groundwater Conditions in Silts and Fine Sands. A Study of Induced Groundwater Changes Based on Laboratory and Full-Scale Field Tests

    Författare :Marius Tremblay; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fine sand; laboratory tests; numerical simulation; silt; soil mechanics; groundwater; pore pressure; field tests; soil matric suction; partially saturated soil; groundwater conditions;

    Sammanfattning : Every day, geotechnical engineers have to deal with groundwater problems. In order to find suitable solutions to these problems, modelling of the groundwater conditions and their variations in time has to be performed. A study of the groundwater conditions in silts and fine sands was made including laboratory and full-scale field tests. LÄS MER

  5. 4. Matrix Suction in Silt and Sand Slopes. Significance and Practical Use in Stability Analysis

    Författare :Anna-Lena Öberg; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Conventional stability analysis in unsaturated silt and sand slopes often results in unrealistically low factors of safety. The purpose of the study was to increase the knowledge and the understanding of the unsaturated zone and its matrix suction in order to facilitate more elaborate stability analyses of silt and sand slopes.

  7. 5. Testing and modelling of silty and sulphide-rich soils

    Författare :Yao Yu; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Sammanfattning : Silt and sulphide soil are two types of soil which are dominating in northern Sweden, especially in the coast area of the Baltic sea. The stress-strain and strength characteristics of these two soils have so far not been as much explored as those for e.g. Scandinavian clays. LÄS MER
