Zusammenfassung |
Rockfall protection embankments are ground levees designed to stop falling
boulders. This paper investigates the behaviour of geocells to be used as
components of these structures. Geocells, or cellular confinement systems,
are composite structures associating a manufactured envelope with a granular
geomaterial. Single cubic geocells were subjected to the impact resulting
from dropping a spherical boulder. The geocells were filled with fine or
coarse materials and different boundary conditions were applied on the
lateral faces. The response is analysed in terms of the impact force and the
force transmitted by the geocell to its rigid base. The influence on the
geocell response of both the fill material and the cell boundary conditions
is analysed. The aim was to identify the conditions resulting in greatest
reduction of the transmitted force and also to provide data for the
validation of a specific numerical model. |
