1. 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
2. Undrained shear strength in clay slopes - Influence of stress conditions. A model and field test study
Sammanfattning : To counteract natural hazards such as landslides, current methods for evaluation of soil properties as a mean for determining the safety level of natural slopes need to be refined. The empirical relationships used for estimation of the undrained shear strength from piezocone and field vane test are based on the stress conditions valid for horizontal ground and normally consolidated or slightly overconsolidated soil.

3. Soil identification by vibration measurements during soil-rock sounding
Sammanfattning : Dynamic penetration tests are frequently used as geotechnical site investigation methods. In Sweden, the main reason to choose a dynamic penetration method is to investigatedepth to bedrock, strength and deformation properties of soil, compaction, or pilingdepth. LÄS MER
4. Soil Erosion and Mass Movement in Agricultural Drainage Ditches
Sammanfattning : Agricultural drainage ditches degrade over time. This degradation is often due to soil erosion, which can cause mass movement (bank failure) when the toe of the bank is eroded or the slope of the bank is too steep. Soil eroded or displaced by mass movement is either transported by the flowing water or deposited in the drainage ditch. LÄS MER
5. Effect of Compactive Effort on the Behaviour of a Gypsiferous Subgrade Soil
Sammanfattning : Presented in this thesis is a study of the effect of compactive effort and long-term soaking on strength, stiffness and deformation characteristics of a gypsiferous subgrade soil from Kirkuk city.The tested soil is sandy lean clay (CL) according to the Unified Soil Classification System and A-6 (6) soil according to AASHTO soil classification system.
