Gabion Basket Stone Wall is an integral gravity mass structure that follows the standard design methodology for gravity retaining walls.
Shengsen always recommends that soil data for stone cage wall design should be based on certified geotechnical soil reports at the site location. Shengsen offers complete gabion retaining wall stability analysis on request.
The total pressure of the stone cage wall must be less than the expected bearing capacity of the soil under the wall. The contact pressure on the foot of the flexible stone cage is not distributed in a planar manner, but rather decreases from a maximum at the resulting result to a smaller value at the base edge. Therefore, the pressure at the toe of the stone cage wall is typically less than the pressure of the rigid wall.
The calculation of the subgrade reaction in the flexible foundation is difficult, and involves errors related to the evaluation of the subgrade reaction coefficient. Suppose this is a safe mistake because it is assumed that the reaction has a planar distribution, as in a rigid wall.
Gabion gravity retaining walls are usually placed directly on a graded soil basis. To increase load carrying capacity, minimize differential settling, and/or allow for additional drainage, a grain-filled base layer with a consistent grade of 1⁄2" - 11/2" can be placed and compacted to a local standard of 6" - 18" in depth as the basis for the placement of the gabion wall.
