In the model area we can create all the stages stages and define all project parameters (external loads, soil nail sections, shotcrete sectionetc.) Build on solid fundamentals on the design of deep excavations, and learn how to minimize uncertainties. Soil nail installation is relatively rapid and uses typically less construction materials than ground anchor walls. All items (shotcrete facing, soil nails, borings, loads etc) can be graphically added on the model area. 2) The value of the weight of criterion for "Types of soil" would be the maximum value applicable to that soil from subgroups "texture", "peat", "industrial waste" and "liquid". The software provides several estimation tools (SPT Estimator andpartial estimation tools for each property using scientific methods and equations). Soil nailing uses grouted steel nails to reinforce in situ soils and create a gravity retaining wall for permanent or temporary excavation support. 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).
