Abstract

Landslides, caused by slope instability, are a recurring problem on the Alóag-Santo Domingo road in Ecuador, causing significant human and material losses. This study reviews slope stabilization techniques using false tunnels, focusing on their effectiveness in mitigating landslides on this road. The main objective is to analyze the effectiveness of false tunnels in slope stabilization and landslide protection. Detailed geotechnical studies were analyzed, including geophysical prospecting using seismic refraction and electrical resistivity. The data obtained were analyzed with specialized software (SLIDE v 6.0 and Phase by Rocscience) to evaluate the stability of the slopes and design the necessary stabilization measures. The methodologies included the MMST method, full-face excavation with deformation control support, and the use of steel fiber-reinforced concrete (SFRC). Geotechnical studies identified critical materials such as sandy silts, colluvium, and volcanic rocks. The implementation of false tunnels, using advanced methodologies, significantly improved the stability and safety of the slopes. These techniques proved effective in managing large deformations and ensuring the integrity of the road infrastructure. The implementation of false tunnels on the Alóag-Santo Domingo road has proven to be a robust and efficient solution for slope stabilization.
