Review article

Nail slope support has proven itself as an effective engineering protection measure, which is used to increase the stability of slopes, and involves the installation of drilling-injection ground nails together with a flexible cover system. The article considers the issue of improving the existing design methodology of this type of structure, which will include an assessment of the overall stability of the slope, an assessment of the local stability of the surface layer, considering soil moisture saturation, checking the strength of the nail on the ground and material, as well as checking the strength of the nail attachment (ground nail and steel network) on slice. To achieve this goal, there was carried out a selection of soil nailing support for the considered engineering-geological section using the Plaxis 2D PC and there was offered an analytical method for calculating slope stability. The authors also propose a method that can be used for assessing the strength characteristics of soils of the surface layer, considering excessive soil water saturation.
