Effects of the Addition of Dihydrate Phosphogypsum on the Characterization and Mechanical Behavior of Lateritic Clay

May 16, 2018
This paper presents the effect of adding dihydrate phosphogypsum, which is a byproduct of the production of phosphate fertilizers, on the mechanical behaviour of a lateritic clay typical of Brazil’s Midwest region. Because of the distinction of the mechanical behaviours of both materials, laboratory experiments were conducted with soil, phosphogypsum and mixture...

Stress-Strain Analysis of a Concrete Dam in Predominantly Anisotropic Residual Soil

July 04, 2018
Studies of foundations for dams should take into account the study of the behavior of the rocky mass, primarily the stresses and strains expected during the construction and post-construction period. When these structures are supported on sound rock, the use of concrete dams is favored. However, when the foundation is made up of soil or soft rock, earth dams are...

Heterogeneity Evaluation of Soil Engineering Properties Based on Kriging Interpolation Method. Case Study: North East of Iran, West of Mashhad

May 16, 2018
Many sciences are confronted with uncertainty in their application field. Therefore, the use of statistics plays an important role for creating a partial model of the whole in most practical cases. Preparing a dispersion map, merging spatial statistics and geographic information systems (GIS), is very useful in geotechnical engineering. Interpolation is one of t...

Case Study: Stability Assessment in Underground Excavations at Vazante Mine - Brazil

June 06, 2018

Currently, most studies on stability of underground excavations include two separate analyses: the elastoplastic behavior of rock masses and/or kinematic analysis of possible wedges and blocks formed in the excavation walls. This paper presents a case study carried out at the Vazante Zinc Mine in Minas Gerais, Brazil, where studies on stability of under...
