Rock and joint alteration leads to modifications in their properties,
resulting in a reduction of rock mass strength and consequently a decrease
in the safety of engineering structures. The alteration process changes the
material and alters its geomechanical behavior. This research presents the
studies conducted to evaluate the mechanical behavior of rock joints in the
gneiss massifs that make up the hydraulic circuit of the Simplicio
Hydroelectric Plant due to their alteration. Compilation and analysis of data
from previous research were carried out to parameterize the joints at
different levels of alteration. Deterministic stability analyses showed that the
alteration process of gneiss joints can significantly reduce the slope safety
factor by up to half of its initial value. Furthermore, probabilistic analyses
revealed an increase in failure probability of approximately 10 percent among the
studied alteration classes. The results underscore the importance of
assessing the level of joint alteration in engineering projects.
