Several methods for prediction of the load-settlement curves of shallow foundations have been proposed based on in-situ testing data. However, the good accuracy of such prediction depends on the definition of appropriate soil stiffness. Seasonal variability and its influence on the soil behavior need to be considered for unsaturated tropical soils. In t...
View ArticleA root pile is an injected type of pile (cast-in-place with pressure, with very distinct construction aspects from the known micropile type). Those piles are installed by using distinct injection pressures up to 500 kPa during the mortar shaft formation. The executive control of root piles is usually carried out by static load tests, requiring a costly ...
View ArticleIncreased food production results in the development and application of agrochemicals to control weeds, which can affect agricultural production. Pesticides contaminate the environment and change soil and water quality. Therefore, to improve the understanding of the adsorption mechanism of 2,4-dichlorophenoxyacetic acid (2,4-D) in aluminoferric red oxis...
View ArticleBased on special engineering geological conditions of a cut-slope area at Heitanping hilly-pass along Yongzhou – Jishou highway, shear creep properties of weak interlayer in this slope (about 30 m deep) have been studied by shear creep test to obtain shear creep curves. Shear creep constitutive model can be obtained by stationary parameter fra...
