This paper investigates slope stability of soil nailed walls which are located on sites formed with mostly residual soils. Residual soils, forming from weathered rocks can be found in many parts of the world with different characteristics and appearance based on type of the parent rock they have been formed of. A review on geotechnical properties of residual soils that have been used in previous studies in different parts of the world will be presented and then evaluated to be used as parameters for numerical analysis of soil nailed walls. Slope stability assessment is performed by LEM analysis and a discussion on the results of analysis is presented in this paper.
