...S. Samanta; K.-H. Yang; S. Rajesh; Y.-H. Fu; C.-W. Wu; H.-M. Wu; R. P. Rajak This study conducted a series of model tests on geosynthetic encased columns (GECs) stabilized slopes subjected to seepage to assess the effectiveness of GECs in enhancing slope stability. The model tests simulated...

...B. V. S. Viswanadham; P. Kumar; R. K. Saran The objective of present study is to evaluate the performance of a levee subjected to flooding and seepage through centrifuge model tests. For this, six model tests were conducted on a 240 mm high levee model at 30 g in a 4.5 m radius large beam...

... of seepage forces on the side-hill fill type of geofoam block configurations. In order to improve the performance of traditional embankment-widening configuration under seepage forces, an alternative geofoam block assembly is proposed. For this purpose, a lysimeter with dimensions of 60 cm high, 20 cm wide...

...O. Akay Lightweight expanded polystyrene (EPS) geofoam (geofoam block) is used in slope remediation works as a soil substitute fill to reduce driving forces that can lead to global instability. On the other hand, the presence of seepage flow requires special attention because geofoam block slope...

... to rainfall was investigated numerically. The analysis was done with and without hybrid-geosynthetic layers embedded in a silty sand slope having 2V:1H inclination with rainfall intensities ranging from 2 mm/h to 80 mm/h. The rainfall was simulated numerically for 24 h, and seepage, deformation and stability...

... to alleviate hydrostatic pressures in geofoam block slope systems. In this study, small-scale laboratory lysimeter experiments investigated the behavior of a stabilized sandy slope with a geofoam block slope system experiencing seepage. An internal drainage system was incorporated by grooving dual drainage...

...A. Rajabian; H. Ghiassian; B.V.S. Viswanadham ABSTRACT: This paper presents the results of centrifuge model testing on slopes reinforced by anchored geosynthetics and subjected to seepage conditions. The tests were conducted on 2V:1H slope models under steady seepage condition at 50 g...

... of geofiber, polypropylene and polyester, were used. In this work, various experiments were carried out to determine the influence of geofibers with various dosages and lengths on the seepage velocity and piping resistance of soil. A fiber dosage up to 0.15% only was adopted. It was observed that geofibers...

... and subjected to uniform seepage. The slope models were brought to failure by gradually decreasing the AGS loads. A comparative analysis of the failed models in terms of the predicted safety factors and slip surface configurations were carried out using limit equilibrium and finite element analyses. Good...

...T. Tao; D.F. Li; J. Yan A geotextile/geomembrane composite liner was placed on the upstream slope of the clay core between the core and rock-fill shoulder to prevent seepage through a rock-fill dam at Zhushou reservoir in China. The paper investigates the coupled effects of stress and seepage...
