| Abstract: | Geogrid‐reinforced embankments on piles or columns: Methods and case studies. Embankments on soft subsoil supported by piles or similar elements and high‐strength geosynthetic reinforcement on top of them have important advantages compared to “conventional” embankment foundation: no consolidation time is required, there is no import/export of additional embankment soil to accelerate consolidation or to compensate the settlement, practically no additional settlement occurs under traffic etc. The application of such solutions is growing recently worldwide. Corresponding design procedures meantime have more than 10 years of history going through significant development, scientific and verification efforts across Europe. A critical overview of these procedures is presented pointing out the increasing precision and reliability. Some typical interesting projects from the last 10 years are briefly described and discussed including both railroad and road applications, different concepts and geosynthetic reinforcements, measurement programs and experience. |
