Adverse Effects of Soil Grouting on Sandy Soils
Applied Mechanics and Materials, 2015Uncontrolled growing of construction industry in Turkey has caused a large number of buildings were constructed without the benefit of sufficient engineering supervision. These phenomena have contributed to the increase in the number of seismically weak buildings.

Proton Buffering and Metal Leaching in Sandy Soils
Environmental Science & Technology, 2005Recent developments in acidification research focused on the leaching of metals from contaminated soil. In this paper the buffering of sandy soils upon acidification is studied in relation to the release of major (Al, Ca, Mg) and trace metals (Cu, Cd, Ni, Zn) from the soil reactive surface.

CHANGES IN THE PROPERTIES OF SANDY SOILS
Конференции, 2021Қумларнинг келиб чиқиши Фарғона водийсининг турли қисмларида бир хил эмас. Ландшафтлар, шунингдек уларни ташкил этган компонентлар ҳам ўзаро узвий боғланган бўлиб, умумий экологик мувозанат холида туради. Қумли даҳаларнинг табиий компонентлари ва суғориладиган тупроқларини тадқиқ қилиш ҳамда уларнинг хосса ва хусусиятларида юз бераётган ўзгаришларни ва

Electric explosions in sandy soil
Combustion, Explosion and Shock Waves, 19681. The kinematic parameters of motion of sand have been obtained for a subsurface electric explosion. 2. It has been shown that there is no qualitative difference in the nature of the motion of the sand following electric and chemical explosions; however, a chemical explosion is a more powerful source for mechanical action than an ...

Spectral reflectance of drying, sandy soils
2014 IEEE Geoscience and Remote Sensing Symposium, 2014A high-resolution time series of the spectral reflectance of drying, sandy soils reveals sensitivities to the drying process that appear to be characteristic of the disposition of water on the surface of the soil. The increase in reflectance is clearly related to the decrease in overall water content, but the spectral details of the relationship are ...

METABOLISM OF DICHLOBENIL IN SANDY SOIL
Weed Research, 1970Summary. A study was made of the breakdown of 14C‐dichlobenil (2,6‐dichlorobenzonitrile) added at 2 ppm to a sandy soil containing 4% organic matter. After 8 months more than half the added herbicide had been metabolized. The major conversion product was 2,6‐dichlorobenzamide (95% of total metabolites).

The Effect of Soil pH on Nitrification in Coarse Sandy Soil
1996The effect of soil pH on the nitrification at low temperatures was studied in a coarse sandy soil. Field incubations were carried out during two winter periods in a field trial with soil pH-values from 4.2 to 6.2. In the laboratory the effect of soil pH on N-mineralization and nitrification was measured after application of liquid pig manure and ...

Journal of Geotechnical Engineering, 1986
Recently soil arching theory has been extended to the study of forces and stresses exerted by a yielding soil mass against discrete piles embedded in a slope and extending into a firm, non‐yielding base. Many uses of discrete pile retaining wall systems exist in current geotechnical practice.

Earthquake resistance of sandy soils
Batiment International, Building Research and Practice, 1981The need to have reliable foundations for potentially vulnerable installations like nuclear power stations has renewed interest in a particularly hazardous phenomenon of some earthquakes. This is when a saturated level sandy soil can behave almost like a liquid as a result of the severe ground motion.

An Effect of Sandy Soils on the Movement in the Terrain
2014An analysis of geographic factors is the primary and necessary step for the preparation of military operations on the territory. Relief, hydrology, soil conditions, vegetation and other factors greatly affect the pass ability of an area and the movement of vehicles in the terrain.
