Abstract

The Tijuana-Ensenada highway crosses the “Salsipuedes Bay”. This zone has been subject to numerous landslides due mainly to geological conditions. The last great landslide occurred on 28 December 2013. The principal causes that triggered the landslide were: the shale weathering, the groundwater, and the seismicity of the zone. In the present study, a deep sensitivity analysis was performed to reproduce the failure mode to understand the failure mechanisms and the factors that triggered the landslide. The results suggest that the seismic activity and water caused the degradation of the shale. To make a close approximation of the real conditions a finite element analysis was carried out using patterns of joints and adopting different shear strengths for the joints. Finally, the failure mechanism was reproduced in a satisfactory form.
