Geomembrane as an Upstream Impermeable Blanket of Embankment Dams - Laboratory and Numerical Study

December 13, 2018

The use of geosynthetics has been a common practice in geotechnical engineering when the improvement of local soil characteristics is necessary. This paper presents an experimental and numerical study of the performance of HDPE geomembrane as impermeable blanket installed upstream of embankment dams, a treatment technique for very permeable foundation. ...

Behavior of Geosynthetic-Encased Stone Columns in Soft Clay: Numerical and Analytical Evaluations

October 24, 2018
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 e...

A Method for Designing Finger Drains and Assessing Phreatic Lines for Dams

October 02, 2018
Finger drains are linear drains used to collect and conduct percolated water in embankment dams. They are arranged crosswise into earth dams, either permanently or as a technique to treat clogged filters. Given their easy operation, they are often applied in engineering practice, without the aid of specific dimensioning techniques in many cases. The aim of this ...

Influence of the Embedded Length on the Overall Stability of Single Anchored Retaining Walls

June 05, 2017

Urban excavations are frequently performed using anchored retaining walls. Overall stability is an important stability verification in such walls and is significantly influenced by geometrical and mechanical characteristics of the wall, of the anchors and of the soil. In the present work, particular emphasis is given to the role of the embedded length i...
