SnailPlusModel Wizard can be used to create any sloped surface with all construction stages, excavations and soil nail and facing installation in minutes. Since considerably more soil nails are used than ground anchors, adjustments to the design layout of the soil nails are more easily accomplished in the field without compromising the level of safety. strengthening of existing grounds by installing. the ratio of resisting force to driving force). Soil Nail Wall Nomenclature (Lazarte, et al, 2003) Outer: Soil Nail Wall Des ign Concrete or Shotcrete Compressive Strength: Soil Reinforcement Type: Soil Reinforcement Size: Soil Reinforcement Grade: Wall Geometry and Design Parameters These calculations are the intellectual property of Steven C. Devin and %%EOF GEO5 enables comparison of two independent solutions. Nail location, inclination, and lengths can be adjusted easily when obstructions (cobbles or boulders, piles or underground utilities) are encountered. SnailPlus has implemented various different standards and specifications for the soil nails and shotcrete facing design. The soil in which the excavation is constructed is able to stand unsupported in a 1- to 2-m (3- to 6-ft) high vertical or nearly vertical cut for one to two days. Tension-resisting steel bars are inserted into the holes and grouted in place. Soil nails can be used in the slope surfaces.
