In the case, a detailed survey of the topography was carried out, geology, and geomorphology. The use of the soil was identified by means of tools to detect satellite images in the software ERDAS IMAGINE 2014. For the geotechnical characterization, engineering field works were carried out by using indirect and direct methods such as: the Electrical and Vertical Polls and Standard Penetration Tests. Susceptibility to landslides was determined through applying the Multi-Criteria and Deterministic methods. The first one was carried out considering an assessment of factors such as Geology, Slopes, Geomorphology and the current use of the soil, using the Analytical Hierarchies of Saaty, an evaluation of the types of factors and using the direct method. All of this, with the help of ILWIS 3.8 and Arc GIS 10.2 software. Resulting 4 degrees of Susceptibility which are: very low (0.09%), Low (48.31%), moderate (41.50%) and high (10.10%). For the deterministic method, engineering parameters required for the calculation of the stability of the soils were calculated, so, normal and saturated sceneries to depths with fails of 1 m and 2 m. were simulated. Establishing that the critical areas (unstable areas and with low stability) of the terrain are generated mainly by influence of water infiltration; specifically those ones at the north and east of the study area. |
