SnailPlus can calculate and report the most critical slope surface and the slope stability safety factor with the use of several scientific methods. Specifications. Shotcrete or concrete is typically applied on the excavation face to provide continuity when a soil nail wall is constructed. There is no need to embed any structural element below the bottom of excavation as with soldier beams used in ground anchor walls. SnailPlus is our soil nail analysis software. Piezometric water input values. Soil nailing is advantageous at sites with remote access because smaller equipment isgenerally needed. The design of soil nail is covered in Section 7.5: Reinforcement of existing ground in BS8006: 1995. For certain conditions, soil nailing offers a viable alternative from the viewpoint of technical feasibility, construction costs, and construction duration when compared to ground anchor walls, which is another popular top-to bottom retaining system. 0000176510 00000 n Soil nailing is a technique used to reinforce and strengthen existing ground.Soil nailing consists of installing closely spaced bars into a slope or excavation as construction proceeds from top down.Soil nailing is a potential solution of landslide problems as it is economical and also applicable in seismic zones.It can solve the problem of residential area up to a great extent.It can be used .
