Streszczenie:

An evaluation of soil-geosynthetic interface friction is important to the design of any anchorage detail of a reinforced soil structure or membrane-lined waste containment facility. A large pullout apparatus has been designed and commissioned to evaluate the mobilization of pullout resistance in geosynthetic test specimens. Sand samples were prepared by pluviation into a rectangular box, 1.30m x 0.64m x 0.60m. A stress controlled top boundary was used to apply vertical stresses in the range 5 to 90 kPa. A rate of pullout displacement of 0.5 mm/min was used in the program of testing. A techniq

Current available methods for the design of unpaved roads, with and without geosynthetics, were used for sixteen full-scale test sections which were constructed at the Bothkennar Soft Clay Site, Airth, Scotland. The full-scale trials consisted of twelve pavements including geosynthetics and four control pavements incorporating two types of aggregate and two design life expectancies. The test pavements were instrumented to monitor the transient stress and strain distribution, permanent strain distribution, geosynthetic temperature and ground water level during the trafficking operation.

Streszczenie:

Geosynthetics, or manmade materials used in soils engineering, have successfully been used as base reinforcement of pavements for over 40 years. Use of geosynthetics can result in cost savings by allowing the aggregate base layer to be reduced in thickness and/or the service life of the pavement to be extended. Design methods for this type of reinforcement have typically been developed by individual manufacturers for specific products. These methods are not widely used by state transportation agencies because 1) they are proprietary, 2) they are empirically based, and 3) they lack compatibilit

Experimental and analytical investigations were performed to evaluate the comparative performance of pavements with and without geosynthetic stabilization. This was accomplished by the testing of a total of 18 pavement sections which could be classified into four different types: one which was constructed without geosynthetics and which served as a control, and three which were stabilized with one of two geotextiles or a geogrid. The pavement sections were constructed to model a typical secondary road in Virginia which is constructed over a silty sand subgrade material. Loading of the pavement

Among the most promising novel methods for treating heavy metal contamination in fine soils is electrokinetic soil remediation - passing a low-voltage current through the soil that causes the target contaminants to migrate to the electrodes where they can be captured, broken down or immobilized. However, the widespread in-situ application of this process as a creative solution for the problem of metal contamination has been prevented because of a variety of problems, some of which are linked to the available electrodes.

Geogrid reinforced structures have been successfully used for over 25 years. However their design procedures have remained largely focused on ultimate failure mechanisms, originally developed for steel reinforcements.

The poor understanding of deformation performance led many design codes to restrict acceptable soils to selected sand and gravel fills, where deformation is not as concerning.

The use of geosynthetics in landfill construction introduces potential planes of weakness.

Repeatability interface shear strength testing of a geomembrane/geotextile interface at low normal stresses suitable for capping systems showed considerable variability of measured geosynthetic interface shear strengths, suggesting that minor factors can have a significant influence on the m

A geocélula foi desenvolvida, inicialmente, com o intuito de melhorar a capacidade de carga do solo. Contudo, este geossintético também é empregado para compor muro de arrimo de gravidade, como sistema de faceamento de estruturas reforçadas, como proteção de taludes contra erosão e como revestimento de canais. Na melhora da capacidade de carga de solos, a geocélula pode ser usada no reforço de fundações, de vias rodoviárias e ferroviárias, e em aterros sobre solos moles. Na literatura existem poucos modelos de previsão da capacidade de carga de solos reforçados com geocélulas, contudo, com lim

The main weakness of soil is its inability to resist tensile stresses. Civil engineers have been trying to address this problem for decades. To increase the tensile and shear strengths of soil, different methods of reinforcing such as using geosynthetics have been used in different types of earth structures such as retaining walls, earth dams, slopes, etc. Due to the excellent corrosion resistance of polymers, the use of geosynthetics has increased dramatically in recent years. However, there are some significant problems associated with geosynthetics, such as creep and low modulus of elastici

El Tramo I del proyecto “Mejoramiento de la carretera Oyón – Ambo” comprende 48, 9 km de longitud y beneficia a 93,878 usuarios entre los departamentos de Lima y Huánuco. El proyecto consiste en una vía con tramos de pavimento flexible y pavimento rígido. A lo largo del diseño se han identificado zonas críticas por las que debe atravesar la vía de las cuales los bofedales son los más complejos. Como medida de solución en el expediente técnico se ha propuesto el uso de geomallas biaxiales y geotextiles además de haber diseñado el pavimento rígido bajo la metodología AASHTO 93. La presente inve

Streszczenie:

Este trabalho apresenta um estudo sobre deformações de geotêxteis ao longo do tempo, considerando interações entre reforço e solo confinante em muros de solo reforçado. O programa experimental desenvolvido para esse fim envolveu duas etapas básicas. Na primeira etapa, um novo equipamento foi desenvolvido na Escola de Engenharia de São Carlos/USP, para a realização de ensaios de fluência com um elemento de solo reforçado. O equipamento desenvolvido permite simular o mecanismo típico de transferência de carga em estruturas de solo reforçado, isto é, o solo solicita o geotêxtil. Esse equipamento
