Albufeiras Na Ilha Da Madeira: (Imprescindível) Impermeabilização Com Geossintéticos
Na ilha da Madeira, existem vários reservatórios de água para diferentes fins, entre eles as albufeiras das barragens de Pico da Urze e da Portela. Estas infraestruturas têm em comum a particularidade de as características das formações geológicas vulcânicas ocorrentes e os materiais de construção das barragens não garantirem a estanquidade necessária para a retenção […]
Interaction Of Geotechnics With Society Through Education
The Federal University of Goiás (UFG) and the University of Brasília (UnB), in partnership with the company Eletrobras Furnas, have developed research and, based on this, extension projects aimed at education in a broad sense, in which they seek to disseminate and popularise technical-scientific knowledge. This paper aims to present and evaluate educational actions carried […]
Pull-Out Response Of A Geogrid Buried In Recycled Sands
Recycled construction and demolition waste (RCDW) has demonstrated geotechnical properties that encourage it to be used in reinforced soil structures (RSS) with geosynthetics. However, the interaction between RCDW and reinforcements needs to be better understood, given its importance for design. This paper presents a qualitative study on the interaction between geogrid and recycled sands by […]
Mechanically Stabilized Wall (Msw) With Geogrids As Complement Of Partially Executed Anchored Wall
This article presents the case study of Wall C11 of Lot 1 in the ringroads of Caraguatatuba and São Sebastião job site, whose original design consists of an anchored retaining wall with a concrete face supported on root piles. At the time of its interruption, only a part of the job had been executed. The […]
An International Initiative On Geosynthetic Education
An international educational initiative to facilitate the exposure of geosynthetics to undergraduate civil engineering students has been conducted by the International Geosynthetics Society (IGS) for over a decade. Geosynthetics is a comparatively new topic within geotechnical engineering and, consequently, has only been sporadically introduced into undergraduate Civil Engineering curricula. In particular, geotechnical engineering professors themselves […]
The Cavity’s Effect On The Bearing Capacity Of A Shallow Footing In Reinforced Slope Sand
This paper presents an experimental and numerical study for the effect of the cavity on the behaviour of a strip footing positioned on a reinforced sand slope. This study used a new type of geosynthetics called fiber carbon and fiber glass. These components have the potential to isolate the soil inside the geosynthetic and prevent […]
An Evaluation Of Reinforcement Mechanical Damages In Geosynthetic Reinforced Piled Embankments
The use of geosynthetic reinforcement in piled embankments over soft soils is an effective solution for the reduction of settlements and to increase the embankment stability. The most efficient position for the reinforcement layer is on the pile cap or head. However, a direct contact of the reinforcement with sharp edges may damage it, compromising […]
Geogrid Mechanical Damage Caused By Recycled Construction And Demolition Waste (Rcdw) Under In-Field Cyclic Loading
Despite the advances observed over the last decade, Brazil still suffers from the scarce use of recycled construction and demolition waste (RCDW). On the other hand, most of the roads in the country are unpaved and present low loading support. In this context, the construction of geosynthetic reinforced unpaved roads with RCDW could stimulate the […]
Circular Footing On Geocell-Reinforced Granular Residue From Precious Gem Processing Over A Sand Bed
Geocell is a tridimensional confinement structure used for soil reinforcement, which significantly improves the performance of foundation systems. Aiming at a more sustainable engineering project and promoting a correct destination of a residual material, an alternative to fill the geocell is through the use of precious gem processing waste. The performance of geocell reinforcement filled […]
Geogrid Mechanical Damage Caused By Recycled Construction And Demolition Waste (Rcdw): Influence Of Grain Size Distribution
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 investigate the […]
Behavior Of Geosynthetic-Encased Stone Columns In Soft Clay: Numerical And Analytical Evaluations
The type of improvement technique that will be applied to a soil beneath an embankment depends on the nature of the problematic soil existing at the site. Soft soils beneath embankments typically present high compressibilities and low shear strengths. In some cases, geosynthetic-encased stone columns (GECs) have shown advantages over other solutions to improve embankment […]
