Projects involving unstable rock slopes are widely recognized in infrastructure engineering as very challenging. This is due to the complexities associated with investigation, evaluation and ultimately mitigation. Many major transportation corridors (roadways/railways) pass through historic, steep-sided cuts, that are difficult to access and maintain.

Mitigation of slope instabilities requires, a sufficient level of effort to collect the needed data to properly evaluate and develop a comprehensive slope stabilization strategy. In addition to the stabilization design, mitigation solutions must account for non-geologic project constraints, including, right-of-way limitations, construction access, environmental sensitivities and protection of the public and stakeholder property.

Best practices are constantly evolving as a result of innovations in investigative methods and technologies, advances in analytical and visualization software and progressive construction techniques. This presentation is based on knowledge gained and lessons learned through recent rock slope stabilization projects located in complex physical and geological environments.
