Landslide is one of the major geo-hazard escorted by uncertainties that give escalation to hundreds of deaths every year.The strategy of slope remediation or stabilization is a common treatment of landslides. At present, safety factor method is agreed to soil nailing design and analysis. In oneway it seems to be the positive assumption. Thus if reliability analysis method is introduced into soil nailed wall design and analysis, a lot of consequences can be mitigated. In this study, the author has targeted the uncertainties; poses threats to soil-nail retaining structure�s reliability. © 2016 Taylor & Francis Group, London.
