Análise de susceptibilidade a movimento de massa em talude na Avenida Pierre Chalita Maceió/AL

Abstract

The identification of points susceptible to mass movements is a significant challenge in the field of geotechnics, due to potential material and human damage. This study presents a vulnerability analysis on a slope located on Avenida Pierre Chalita, Maceió/AL, which was assessed as presenting a very high risk for mass movements (classification R4). Based on a field visit, factors such as the terrain's slope, soil characteristics, presence of water and disorderly occupation were evaluated to identify the critical points that provided greater vulnerability to landslides. The results obtained in this research demonstrate the importance of applying vulnerability analysis techniques to prevent mass movements in independent urban areas. From the understanding of the risk factors, technical solutions can be proposed designed to minimize the effects of natural disasters in urban areas and, thus, guarantee the safety of people and the preservation of material and environmental resources. After analyzing the intervening factors in the mass movements on the slope of Avenida Pierre Chalita, the Risk Rating R4 was reached, which represents great susceptibility to landslides on the chosen slope. The possibility of involving the residences close to the slope is considered high. In this sense, the implementation of slope stabilization measures is a priority to minimize the risk of landslides. The use of measures such as re-sloping, drainage devices and revegetation are part of the proposal presented as a mitigating measure for the slope.
