Structural changes in latosols of the cerrado region: II - soil compressive behavior and modeling of additional compaction [PDF]

Revista Brasileira de Ciência do Solo, 2011
Currently in Brazil, as in other parts of the world, the concern is great with the increase of degraded agricultural soil, which is mostly related to the occurrence of soil compaction.

The Tension-Shear and Compression-Shear Joint Strength Model for Unsaturated Clay and Its Application to Slopes

Frontiers in Earth Science, 2022
The capillary component and adsorptive component of matric suction differently impact the soil strength. Due to the cavitation effects of pore water, the adsorption effect dominates the behavior of soil when matric suction exceeds the cavitation tension.

Influence of the Duration Compression Ratio of the Input Motion on the Seismic Response of a Soil–Pile–Bridge Structure System in Shaking Table Tests

Applied Sciences, 2022
In the shaking table test of a soil–pile–bridge structure system, it is difficult to keep the similarity relations of the model structure and that of the model soil consistent.

Monitoring the Response of Roads and Railways to Seasonal Soil Movement with Persistent Scatterers Interferometry over Six UK Sites

Remote Sensing, 2017
Road and rail networks provide critical support for society, yet they can be degraded by seasonal soil movements. Currently, few transport network operators monitor small-scale soil movement, but understanding the conditions contributing to ...

Study on the Internal Mechanics and Energy Characteristics of Soil under Different Failure Modes

Applied Sciences, 2023
Under uniaxial compression, the soil mass may be subjected to transverse tensile splitting or swelling failure. This failure is caused by the tensile stress in the soil; that is, part of the vertical stress is converted into lateral stress.

Compressibility of Oxisol aggregates under no-till in response to soil water potential Compressibilidade de agregados de Latossolo Vermelho sob plantio direto em resposta ao potencial da água do solo

Revista Brasileira de Ciência do Solo, 2009
The system of no-till sowing stands out as being a technology that suits the objectives of more rational use of the soil and greater protection against the erosion. However, through till, any of it, occurs modifications of the soil's structure.
