Bottom Reinforcement in Braced Excavations: Coupled Analysis and New Method for Basal-Heave Stability Study

May 26, 2020
Soil-cement bottom reinforcement is commonly used in braced excavations in soft soils, so that ground displacements can be reduced and excavation safety against bottom failure increase. However, there is a lack of studies in the literature regarding such reinforced excavations in which the stability against bottom heave is analysed through mechanical-hydraulic c...

Relationship Between Shear Wave Velocity and Piezocone Penetration Tests on the Brazilian Continental Margin

May 12, 2020

A detailed characterization of the shear wave velocity profile is an essential tool in the resolution of a variety of seismological and geotechnical engineering problems. The main objective of this study is to present equations capable of providing reliable shear wave velocity profile estimations based on CPTu parameters. The results of a series of pion...

Experimental Study of the Group Effect on the Bearing Capacity of Bored Piles in Sandy Soil

October 01, 2019

A foundation design must meet at least the following basic requirements: a) acceptable deformations under the working conditions; b) adequate safety against soil failure; and c) adequate safety against failure of structural elements. For the pile design, depending upon the spacing adopted among them, a pile may affect the other’s behavior. Thi...

Geogrid Mechanical Damage Caused by Recycled Construction and Demolition Waste (RCDW): Influence of Grain Size Distribution

April 06, 2020
Recent studies have shown that recycled construction and demolition waste (RCDW) can be used as backfill material in geosynthetics reinforced soil (GRS) structures. However, besides the environmental and economic benefits of this practice, it is necessary to evaluate the mechanical damages that RCDW could cause to the reinforcement elements. This study aims to i...
