1. Compaction- and strength properties of stabilised and unstabilised fine-grained tills
Sammanfattning : Fine-grained soils are often regarded as problematic soils in earthworks because of their water- and frost sensitivity. Only limited amounts of fine-grained tills are used as earthwork material today. LÄS MER
2. Soil Degradation of Raised-beds on Orchards in the Mekong Delta Field and Laboratory Methods
Sammanfattning : Soil degradation is a complex process which may occur anywhere and at any time. It directly affects the physical, chemical and biological processes within the soil profile. Soil degradation can either be as a result of natural hazards or due to manmade actions, such as mismanagement on cropping patterns, soil preparation and cultivation practices. LÄS MER
3. Excavation in moraine and dense non-cohesive soil : Numerical analysis of soil behavior
Sammanfattning : Excavation and moving of soil are common civil work tasks connected to the construction of buildings, roads and railways. In construction projects large amounts of soil have to be handled with different machines, tools and working methods. Soils are more or less difficult to excavate depending on their properties.

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.
