Abstract
The Mil Cumbres highway was built in the 1940s to connect Mexico City with Morelia. Today, it is an old road with little maintenance and conservation, which has presented various slope instability problems.
In this study, a geomechanical analysis of the slope located in the section km 207+234 (Mexico-Morelia) is addressed, due to the fact that different instability events have occurred including the fall of blocks of different sizes since the rainy season in 2013. The study consisted of in-situ data collection, laboratory work, and the application of the Bieniawski and Romana methods to characterize the slope material. In addition, the Dips software from Rocscience ® was used to expose the main failure mechanisms of the rock mass of the slope and identify mechanisms for its stabilization.
From the results of the analysis, different stabilization strategies were proposed to mitigate the fall of materials from the slope.
