1. Slopes in soft clay - management of strength mobilisation
Sammanfattning : Many natural and man-made slopes close to buildings or infrastructure do not demonstrate sufficient levels of safety with respect to their stability. Nonetheless, it is a requirement from society that the environment we live in is safe. LÄS MER
2. On Rate-Dependency of Gothenburg Clay
Sammanfattning : On Rate-Dependency of Gothenburg ClayMATS OLSSONDepartment of Civil and Environmental EngineeringDivision of GeoEngineeringChalmers University of TechnologyABSTRACTLong-term settlements in clay constitute a major engineering challenge in areas with deep deposits of soft clay. This dissertation aims to extend the understanding and theoretical framework of rate-dependent soil behaviour, so that uncertainties in predictions of long-term settlements are significantly reduced.

3. 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. The Unloading Modulus of Soft Soil: A Field and Laboratory Study
Sammanfattning : Improved infrastructure in urban areas often necessitates underground construction, where the unloading behaviour of the soil is of importance for predicting the amount of heave and how long it will take for the soil to swell. It is of particular interest to study the need for the installation of tension piles, as well as whether the tunnel will be subjected to settlement or heave in the long term. LÄS MER
5. Effects of deep excavations in soft clay on the immediate sourroundings-Analysis of the possibility to predict deformations and reactions against the retaining system
Sammanfattning : When excavating in an urban environment, the evaluation of the magnitude and distribution of ground movements is an important part of the design process, since excessive movements can damage adjacent buildings and utilities. In order to minimize movement of the surrounding soil, a retaining wall support system is used for deep excavations to provide lateral support. LÄS MER
