Examining the Stability of Rock Slopes Stabilized by the Nailing System

Stability studies on rocky slopes, which are an example of geotechnical structures, is regarded as one of the most decisive engineering fields for designers. The significance of this field is immense to the extent that any malfunction of these structures may generate irreparable damages. Unpredictability and variability of physical and mechanical properties of soils and rocks, as well as errors made in measurements, has brought forth the application of reliability-based analyzes in geotechnical engineering into further consideration. Accordingly, stone gables are modeled, and their respective rock slope stability under the force of the dynamic load is examined in this study. Moreover, if the slopes are determined to be unstable, an adequate and optimal method will be devised and proposed by means of using a net to ensure their stability. A stone gable with slope angles of 10, 20, and 30 degrees was subject to analysis, and the gable's stability was evaluated with the aid of manual methods. Subsequently, the stone gable's finite element model, in a two-dimensional state, is constructed via phase.2 software, and the rock slope stability assessment is conducted under static and dynamic conditions. Following, the stability of the stone gable is similarly examined and assessed by placing the net with the rock bolts. Remarkably, the arrangement analysis of bolts is also performed in the course of the rock slope stability evaluation of the stone gables under the force of dynamic and static loads.
