Proper anchoring is critical to how well the geocell will perform in any given application. No matter which method is selected, it must be left in place throughout the life of the project.
The following factors must be taken into consideration:
- Degree of slope
- Length of slope
- External loads, such as snow
- Angle of internal friction of the fill material and slope soil (smaller of the two will be used)
- Unit weight of the material used as fill
- Height of geocell
- Presence of geomembrane
Before selecting the anchoring method, it is necessary to calculate the Net Sliding Forces, or the force which has to be
overcome to keep the geocell from sliding or moving. If the NSF is negative, then the friction between the geocell and slope is sufficient to hold the system in place.
