In this investigation, the protection works proposed by EGEMSA were evaluating based on the danger of the area identified as susceptible to the occurrence of landslides in sector 1 of the project "Protection works of the key yard of the Machupicchu hydroelectric power plant" in the district from Machupicchu, province of Urubamba. The methodology consisted of geotechnically characterizing the slope of sector 1 on El Calvario hill; to evaluate its stability by means of a simulation of the present mass movements, then proceeded to estimate the danger of landslides in the area by means of the hierarchical analysis process. For this, the conditioning factors of the study area (geology, geomorphology and slopes) were considered and as triggering factor abnormal rainfall with a percentage in relation to its climatological standard normal (average scenario of meteorological conditions of the place). Then, the protection structures proposed by the company EGEMSA to stabilize the slope of sector 1 of the project were evaluating with criteria of serviceability limit state (SLS) (When the structure no longer fulfills its function) and the ultimate limit state (ULS) (When the structure collapses). In the analysis of the results, was possible to determine that the area has a very high risk of landslides. It was determined that the most critical slope has FS = 0.426. This slope is the one that was reinforcing with the protection works. It was determined that the protection works reinforce the slope, but only in its area of influence, in the area of influence the FS=0.691 increases considerably by the gabion to FS=5.587. Finally, it was determined that the protection works do not meet their purpose of providing security, so an alternative of structures that do meet the criteria is proposed.
