Modeling of a Slope Reinforced by an Anchored Geomat System to Investigate Global Loading Behavior and Slope Stability
Publication: International Journal of Geomechanics
Volume 23, Issue 8
Abstract
Flexible reinforcements are a promising option in slope engineering owing to their mechanical strength and ecological restoration. An in-depth understanding of the mechanical behavior of a slope reinforced by an anchored geomat system is required to analyze the slope stability and to optimize engineering design. In this study, physical modeling experiments are conducted to investigate the global performance and ultimate capacity of the reinforced slope under different loading levels. A stability model of the reinforced slope and the corresponding computing method are proposed based on a limit equilibrium framework in integral form. Subsequently, the contribution of a flexible protection system and its components to safety factors are quantified against loading tests. The results show that lateral deformation is concentrated in the middle of the reinforced slope, from which the potential failure surface can be derived. The stability enhancement of the reinforced slope is primarily attributed to the anchor bolts, and an increase in cohesion and internal friction angle increases the safety factor more significantly under low-level overloads. This study provides a benchmark for slopes reinforced by an anchored geomat system, which is promising for application in slope engineering.
