[ 1 ] - An Experimental Investigation into the Arching Effect in Fine Sand
In the current paper results of a well instrumented experimental procedure for studying the arching effect in loose and dense sand are presented. The apparatus comprises concentric circular trapdoors with different diameters that can yield downward while stresses and deformations are recorded simultaneously. As the trapdoor starts to yield, the whole soil mass deforms elastically. However, afte...
[ 2 ] - Gypsum Dissolution Effects on the Performance of a Large Dam (TECHNICAL NOTE)
Upper Gotvand dam is constructed on the Karun River located in the south west of Iran. In this paper, 2D and 3D models of the dam together with the foundation and abutments were constructed and several seepage analyses were carried out. Then the gypsum veins scattered throughout the foundation ground and also the seepage pattern were included in the models, hence the dissolution law of gypsum, ...
[ 3 ] - Geotechnical Properties of Lacustrine Carbonate Sediment
Results of laboratory tests on specimens produced from subsoil studies were evaluated tocharacterize geotechnical properties of Tabriz Marl. It was concluded that, Tabriz Marl may be considered as a high liquid limit silt or clay (MH & CH). Range of changes of index, physical and mechanical properties of the Tabriz Marl are comparatively vast. Correlation between these properties has been intro...
[ 4 ] - Compressive Strength Freeze and Thow Durability Correlation in Soil Cement Design (RESEARCH NOTE)
This paper explains the procedure and results of an experiment on the relationship between the unconfined compressive strength and percent weight loss due to freeze and thaw durability test of laboratory compacted soil-cement specimens. The tests were carried out on soil cement mixtures of 10 different soil types. It was shown that the percent weight loss due to freeze and thaw durability test ...
[ 5 ] - Lime and Distilled Water Treatment of Dispersive Soils by Electroosmosis Effect (TECHNICAL NOTE)
This paper explains the procedure and results of electro osmosis treatment of a dispersive soil. A number of cylindrical specimens of a dispersive soil were subjected to the electro osmosis effect and the subsequent cation changes in the soil, inlet water and outlet water were measured. The tests were carried out using distilled water and lime extract in anode. It was observed that with distill...
