DYNAMIC TESTS OF FROZEN SAND SOILS

Problems of Strength and Plasticity, 2019
The study of the laws of contact interaction of hard and deformable impactors with frozen soils is of great scientific and applied value. In solving such problems, numerical methods are widely used. For numerically modeling the behavior of frozen soil under dynamic loading, it is necessary to use models of soil media that adequately describe their ...

LIQUEFACTION RESISTANCE OF SAND MATRIX SOILS

Jurnal Teknologi, 2015
Numerous researches have been focusing on the roles of fines in liquefaction resistance of sand matrix soils (sand dominant soil that contains little presenting fines). It has been reported that the presence of plastic fines would either imposed additional liquefaction resistance of sand matrix soils or caused reduction to the liquefaction resistance ...

Characterization, agricultural potential, and perspectives for the management of light soils in Brazil [PDF]

Pesquisa Agropecuária Brasileira, 2016
Light soils occupy 8% of the Brazilian territory and are especially expressive in the new and last agricultural frontier in Brazil: the Matopiba region - in the states of Maranhão, Tocantins, Piauí, and Bahia -, where they represent 20% of the area ...

Two-dimensional study of the inclusions of skirt sand and deep cement piles to improve the load‒displacement behavior of circular foundations on soft clay soil

Heliyon, 2023
The bearing capacity of clayey soils is low, and the induced settlements play an important role in estimating the stability of structures built on these weak soils. Therefore, these clayey soils need improved mechanical strength.

Spodosols pedogenesis under barreiras formation and sandbank environments in the south of Bahia Pedogênese de espodossolos em ambientes da formação barreiras e de restinga do sul da Bahia

Revista Brasileira de Ciência do Solo, 2010
Morphologically differentiated Spodosols usually occur in the Coastal Plain of the South of Bahia and North of Espírito Santo. They are found in profiles known as "muçungas", i.e. sandy soils that accumulate water. In these areas, two kinds of Spodosols,

Soil structure of sand quarries territory [PDF]

E3S Web of Conferences, 2020
Anthropogenic activities are one of the leading factors of soil differentiation. Significant changes in the soil cover occur as a result of the construction of quarries. The mining industry causes the complete degradation of soils in large areas, the change of the natural soil cover and elevation around the quarries, the destruction of vegetation ...

Improvement of geotechnical properties of silty sand soils using natural pozzolan and lime

International Journal of Geo-Engineering, 2018
In this study the effect of different amounts of lime and natural pozzolan on geotechnical properties of a silty sand soil has been investigated. To do this, 20 treatments were prepared with adding five lime levels of 0, 1, 3, 5 and 7% (by weight) and ...
