Abstract

The research object of the present article is focused on the analysis of instability in the hillside in a section of the road NIC-7, which connects the towns of Juigalpa and Santo Tomás in the department of Chontales The methodology used was based on the determination of parameters which go due to the formation of slidings, among them: the lithology, meteorization, slope angle, fracturing of rocky bodies and precipitation as a detonating factor, illustrating through models on 2D through software a possible landslide, in order to prove the conditions of the slope and the security factor designating the state of the hillside under research. The results obtained in the laboratory tests, showed that the materials in this case soil and rock have low mechanical resistance parameters such as: friction angle, cohesion and weight, when carrying out the modeling in the software, low safety factors are presented due to the conditions of the materials, degree of slope, added to this the weight of structures and vehicular traffic. In conclusion, the state of the slope on the section of the Nic-7 road (km 177-178) is unstable and unsafe.
