Abstract: The effect of the ground anchor in the large slope stability application is usually underestimated. To improve the estimation in the slope remediation projects, a new approach that considering the bending moment capacity of the anchor is presented. The numerical simulation results indicate that, before the slope excavation, both models that with/without bending moment capacity have the same performance. After the slope excavation, the ground anchors that considering bending moment effects are significantly different from the other models. The new model has significant effect on the reduction of the plastic zone development and minor principal stresses and restriction of the slope deformations.
