Different Slope Stabilization Methods

Driven Cantilever Piling

Typically, these elements are driven along the top of the problematic slope. They usually consist of H-piles installed vertically or on a battered inclination to serve as “shear pins” through the failure surface of the slide mass. If an additional shoulder is required, lagging can be installed within the upper few feet to help hold this material in place.

Drilled and Socketed Piling

This system is very similar to driven piling except that the piling is inserted into a drilled hole through the soil and preferably into bedrock. The depth of the socket into the bedrock depends on the rock quality, pile size, pile type, and slide mass driving force. Once installed, the remaining drill hole is filled with grout.

Soldier Pile With Tie-Back Anchors

Repairs of this type are often required when the size of the slide mass is large or when a relatively high factor of safety is warranted. This consists of a row of piling (driven or drilled) with lagging (timber, concrete, or steel) and typically includes a waler installed along the down-slope face. Tie-back anchors (tendons or bars) are then drilled within the bays of the wall (between piling) and drilled into competent rock. The anchor depth or length is a function of the required “bond” length.
