Introduction

Tie-back anchors are a common stabilization method for steep excavations (Figure 1). The anchors transfer the load on the wall deeper into the ground behind the wall. From a limit equilibrium perspective, the loads in the anchors are converted to forces acting on the potential sliding mass. The magnitude and application location of these loads must be determined for a stability analysis.

This example demonstrates how to simulate anchors in a SLOPE/W limit equilibrium analysis and provides recommendations for good modeling practice.
