A influência da sucção na deformabilidade de subleitos rodoviários: efeitos da variação de umidade, método de compactação e gênese dos solos
(Universidade Federal de Santa MariaBrasilEngenharia CivilUFSMPrograma de Pós-Graduação em Engenharia CivilCentro de Tecnologia, 2020-12-04)
This thesis presents a study on the influence of suction on the resilient and plastic
characteristics of highway subgrade soils. The main focus was to evaluate the variation of
suction as a function of postcompaction ...
Shear modulus G(0) and its correlations with matric suction, unconfined compression strength and tensile strength of an unsaturated residual soil
(Ios Press, 2015-01-01)
Several studies have been developed aiming to understand the behavior of saturated natural soils under small strains. A few studies have considered unsaturated soils, in most cases compacted soils and, eventually, disregarding ...
Weathering effect on the small strains elastic properties of a residual soil
(Springer, 2019-04)
Residual soils in the northeast Argentina, southeast Paraguay and central and southern Brazil are the result of the weathering of a near-surface basalt formation. To assess the effect of weathering on the small and large ...
Evaluation of the self-cemeting effect of Construction and Demotion Waste (CDW) on mechanical performance over time for pavement support layers purpose

On the effects of soil properties on leak noise propagation in plastic water distribution pipes
(2018-08-04)
In many countries, leaks are located in water distribution pipes by using the cross-correlation of pipe vibration measured either side of a suspected leak. However, in modern plastic pipes this can be problematic due to ...
Comparison between resonant-column and bender element tests on three types of soils
(Universidad Nacional de Colombia Sede Medellín, 2013)
The bender element (BE) test is used in laboratory to obtain the shear wave velocity of soils. Different execution and interpretation techniques have been proposed. However, there is not a specialized technique with an ...
The influence of saturation degree on soil elasticity modulus: application on prediction the reach of rockfallsInfluência do grau de saturação no módulo de elasticidade dos solos: aplicação à previsão do alcance em quedas de blocos de rochas
(Universidade de São Paulo, Instituto de Geociências, 2018)
Estudo da interação solo-estaca sujeito a carregamento horizontal em ambientes submersos
(Universidade Tecnológica Federal do ParanáCuritibaPrograma de Pós-Graduação em Engenharia Civil, 2012-12-21)
This work aims to make a study of the soil-pile interaction in submerged environments. For the analysis we used the following conditions: two types of piles, concrete pile and composite pile (steel pipe filled with concrete), ...
Microestrutura de um argissolo com aplicações de biochar de arroz e soja
(Universidade Federal de Santa MariaBrasilAgronomiaUFSMPrograma de Pós-Graduação em Ciência do SoloCentro de Ciências Rurais, 2019-02-25)
The addition of organic compounds to the soil causes different effects on its structure, either at the macro or microscale. But the extent of these effects is closely related to the molecular structure of the added organic ...
