A Simplified Method for Analysis of Geosynthetic Reinforcement Used in Pile Supported Embankments
The inclusion of geosynthetic reinforcement in the piled embankment can help transfer loads to the piles and reduce total and differential settlements. In order to select the appropriate reinforcement material, the reasonable calculation of the deflection and tension is very important. Current design methods usually do not represent the true three-dimensional (3D) nature of the displacements, s...
متن کاملGeosynthetic Reinforcement for Embankments over Degrading Discontinuous Permafrost Subjected to Presstressing
Failures of road embankments on discontinuous permafrost commonly occur during thawing of the foundation soil. As an approximation, weak zones created by thawing of discontinuous permafrost can be considered as ‘voids’ within the foundation. Geosynthetic reinforcements have been used to bridge these ‘voids’ and provide support to the embankment fill. This paper presents results of a numerical i...
متن کاملRecent research and development of ground column technologies
In recent years, ground columns, such as vibro-concrete columns and geosynthetic-reinforced stone columns, have been increasingly used to support superstructures and embankments when they are constructed on soft foundations. Several new column technologies have emerged, including different shapes of concrete columns and composite columns. The column technologies have also been combined with oth...
متن کاملGeosynthetic Materials and its Properties for Reinforced Earth Structures
The national planners have put infrastructures development on priority. This has resulted in transport planning widening of National Highway and new roads in country. Thus work of Retaining Earth (RE) structures/ slopes will be going to design in very large numbers over different areas. The availability of backfill material compatible with geosynthetics reinforcements and economy in both has be...
متن کاملBenefits of geosynthetic reinforcement in widening of embankments subjected to foundation differential settlement
In the present study, physical model tests were conducted to investigate the effect of the geogrid reinforcement on the reduction of the differential settlement in widening of a highway embankment. A water bag filled with water and placed beneath an embankment was used to simulate the soft foundation of the widened portion of the embankment in the physical model test. Water from the water bag w...
