1. Effects of deep excavations in soft clay on the immediate sourroundings-Analysis of the possibility to predict deformations and reactions against the retaining system
Abstract : 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. READ MORE

2. On the long-term behaviour of tension loaded piles in natural soft soils
Abstract : The complexity and scale of new infrastructure projects have challenged the current geotechnical design practice. Urban areas are growing at a fast pace in the horizontal and vertical direction, with taller buildings and deeper underground constructions in already densely populated areas. READ MORE

3. Preconsolidation Pressure of Soft, High-plastic Clays
Abstract : In the early days only the ground that was best from a geotechnical point of view was used for foundations, but now, owing to the growth of cities and to the rising prices of land, softer and more compressible soils, less suitable for foundations, are also often used.The choice of foundation method is both economically and technically an important matter, and thorough testing of the soil is often needed to determine its geotechnical properties, and thus, to furnish necessary information.

4. On Rate-Dependency of Gothenburg Clay
Abstract : 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.

5. The Unloading Modulus of Soft Soil: A Field and Laboratory Study
Abstract : 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. READ MORE
