Levantamento de manifestações patológicas características de construções afetadas por movimentos de terra no Bairro Pinheiro, Mutange, Bebedouro, Bom Parto e adjacências

Abstract

The geological phenomenon of an anthropic nature due to rock salt mining affected several neighborhoods in the city of Maceió, creating a subsidence region and consequently compromising many buildings. Because of this, several ones had to be abandoned due to the assessed risk. In order to characterize such pathological manifestations, the present work evaluated two educational buildings restricted from use because of this problem. Surveys were carried out to identify, quantify and qualify the fissures found, in order to obtain information about their configuration. From these data, a fissure map was also drawn up, which helped with the understanding of the state of those buildings and with the characterization of the features found. The pathological manifestations found were predominantly fissures located on the floor in the N–S, NNW–SSE and NNE–SSW directions. According to the observed characteristics, the existence of tensions applied to the elements that are in accordance with the subsidence mechanics was interpreted, showing the possible effect of this phenomenon in the analyzed buildings
