Now, this is a bold statement but please spend a few minutes with us you will find out why! A new approach to Soil Nailing design. Since 2003, experience has accrued in respect of the design and construction of soil nails for upgrading loose fill slopes. According to the experience of several authors, under certain conditions soil nail facing systems can be developed with nails using steel mesh fabric (flexible structural facing). It is called Soil Nail because it's like having a nail being hammered into the soil, where the nails are the steel bars. Following empirical constraints on the design analysis nail ength pattern are therefore recommended for use when performing the limiting equilibrium design calculations: a) Nails with heads located in the upper half of the wall height should be of uniform length. . A simple design approach was introduced a few . There are many ways to stabilize an excavation: sloping, soil nails, rock bolts, gravity walls, earth-retained walls, bins, cribs, speed shores, ring beams, and piling to name a few methods.
