Análise em elementos finitos e equilíbrio limite de taludes com solo grampeado em malha quadrada

Abstract

applied in the stabilization of slopes and embankments. This study aims to analyze the behavior of slopes with different square mesh spacings, seeking to optimize the stability of such structures. A 2D stability analysis was carried out for a 12-meter-high slope with an inclination of 1(H):3(V), reinforced with soil nails in three spacing configurations (Sv,h=0.8, 1.0 m; and 1.2 m), using two methods: limit equilibrium and finite elements with a stress–strain approach. The results showed differences in the failure surfaces and horizontal displacements. The reduction in nail spacing improved overall stability and met verification parameters in accordance with international codes. When analyzing the critical Strength Reduction Factor (SRF), the models with wider spacing exhibited greater displacements. Thus, this study highlights the importance of using multiple analysis methods to achieve safer and more effective design solutions.
