Soil nail wall design is tailored to the necessary strength and service load limits of the project by varying soil nail length, diameter, and spacing. Safe Bearing Capacity has the following significance regarding the soil, The Soil tends to deform when stressed due to loading.The soil deformation depends upon factors like water content, bulk density, angle of internal friction, and the manner in which load is applied on the soil. It is used for slopes, excavations, retaining walls etc. As soil nail construction requires temporary stability in both the staged excavation and also the drilled hole stability, any soils with sufficient temporary self-support of about 2m sub-vertical height for minimum of 1 to 2 days and hole stability for minimum four hours are considered suitable ground for soil nailing. Thirty-eight patients treated with coated nail (ETN ProtectTM, Synthes) were included in the study.
