Abstract: Based on the geotechnical investigation data on a rock slope for the proposed Methanol Olefins project, the natural topographical conditions, hydrological conditions, physical and mechanical properties of rock samples, the potential failure modes of the rock slope are analyzed. The stability analyses are performed on the representative sections. As a result of these analyses, the stability mitigation method is able to be optimized. Both the safety and cost effectiveness are achieved.

Key words: Rock Slope Failure Modes, Stability Analysis, Ground Anchors
