Anchor Trench

L X H =

The upper edge of the geocell should be buried in an anchor trench to prevent flow underneath. This also serves to anchor the geocell to the top of the slope. This method takes advantage of the weight of the soil on top of the buried cells. The following equation can be used to calculate the required length and height of the trench to resist the sliding force:

Net Sliding Force x Factor of Safety

Unit Weight of Soil x tan N

Where N is the angle of internal friction of the fill, or of the surface soil, whichever is lower

If the slope is longer than the panel length, lower panels must also be toed in or attached to the upper panel, or anchored using another appropriate method.

Before opening the sections, drill holes where the tendons are to be located. Thread the tendons through the holes and washers or holes in batten strips at the bottom of the lowest panel. Tie off the lower end of the tendon. Stretch the section, being careful the tendons stay in the holes.

Position the sections and then tie the tendons to a supporting structure above the crest of the slope. This could be a grade beam or other structure designed to support loads. Instead of a structures, the tendons could be tied to earth anchors installed beyond the crest of the slope.

In order to avoid stress concentrations, a large number of light anchors are preferable to a smaller number of heavy anchors. Use of large washers or batten strips helps relieve point stresses where the anchors are attached.
