Collapsible soils are susceptible to high and relatively sudden volume change after wetting under a specific load. They tend to have a high initial void index (more than 40%), a low saturation degree (less than 60%), a high silt content (greater than 30%), and quick softening after reaching humidity (loss of bonding). Due to the settlement of the u...

Loessial soil is moisture-sensitive soil susceptible to settle when fully saturated. In this study, efforts were made to investigate the effect of oil pollutants on mechanical behavior of soil. The loess soil was contaminated by 2,4,6,8 and 10% dry weight of lamp oil and gasoline. Atterberg limits, direct shear, unconfined compressive strength (UCS...

The main purpose of embankments is to protect the land which lies behind them from the effects acting on the waterside of the structure. To function as a safeguard, levees have to have two main features; (i) structural resistance and integrity, (ii) the retaining embankments have to have a certain level of water tightness. On the Great Hungarian pl...

Investigation of a subject usually means that the tools of some field of study are used in order to obtain information. When similar disciplines, such as geotechnics and soil sciences are evaluating the same object, the diverse ways of collecting information leads to different conclusions. However, they study the same subject, only from distinct po...

The term "dispersive soil" refers to a specific type of cohesive soil, which has an unfavorable behavior when it comes to interaction with relatively pure water. While usually the established method in the embankment construction is to use an impermeable material to prevent seepage problems, it is not an adequate solution when the fill material is...

When it comes to flood protection, the established method is to use an impermeable material in dikes, to prevent seepage. This material is usually some type of clayey soil which is considered as watertight and erosion-resistant. Despite that, in many occasions not only seepage, but the failure of the dam occurred due to surface erosion, because dis...

Thixotropy is the reversible change of the materials rheological properties caused by external mechanical forces. Materials with this behavior can be found at several areas, nevertheless the examination of the phenomenon is rare. Materials like paints, or ketchup can show thixotropic behavior, but in this paper pays attention to geotechnically rele...
