From page 80... ... Soil nail walls are top-down construction structures that are particularly well suited for ground conditions that require vertical or near-vertical cuts. Favorable ground conditions ma ke soil nailing technically feasible and cost effective, com pared with other techniques, when: • the soil in which the excavation is advanced is able to stand unsu p ported in vertical or nearly vertical, 3- to 6-FT high cuts for one to two days; • all soil nails are above the groundwater table; and • the long-term integrity of the soil nails can be maintained through corrosion protection.
