Multiple slope angles (including two slopes below wall). Soil nailing uses grouted, tension-resisting steel elements (nails) to reinforce in situ soils and create a gravity retaining wall for permanent or temporary excavation support. DeepXcav is a software program for the design of embedded earth retaining walls with limit-equilibrium and advanced non linear elastoplastic analysis methods. In BS8006, the two-part wedge method and the log-spiral method is recommended for analyzing the stability of soil nailed slopes. Ask A Question. B.3.1 The design of a soil nail concerns mainly the ability of the nail: B.3.2.1 There are three main aspects influencing the performance of the soil nail structure: B.3.2.2 The pullout resistance of the soil nail can be determined, either by estimation from measured ground properties (laboratory tests or field tests), or established directly from measured properties (nail load tests).
