18. Layout Needed to Resist Rotational Failure: This window can be accessed from the previous one. It shows the minimum required length to resist rotational failure considering compound and internal failure. Also shown are all the internal slip surfaces (top-down approach). The red tips are the lengths needed to resist pullout. Note that ReSlope assumes that the reinforcement can develop its strength at its front-end (i.e., at the face of the slope) thus eliminating the possibility of surficial instability). This can be achieved by the use of some facing (e.g., wrapped around, gabions, concrete panels, etc.).
