SUMMARY:

Collapse and expansion soils are responsible for pathologies in various engineering works, leading to financial losses, delays in the schedule, and dissatisfaction among residents. The identification and analysis of the behavior of collapsible and expansive soils aims to establish guiding measures regarding the use and occupation of the soil, as well as preventive measures regarding the planning stages of an enterprise. Technological advances have contributed to the emergence of tools that facilitate the establishment of these measures, such as: Geographic Information System (GIS), Business Intelligence (BI) and Cloud Computing (CN). Based on these technologies, the outlined objectives encompass the  construction of the Special Soils Database (BANDASE) using Google Sheets, the elaboration of susceptibility maps through the QGIS program, the creation of Business Intelligence (BI) dashboards using Google Looker Studio, and the development of applications through Google Earth Engine. The geotechnical data repository resulted in 267 records of collapsible soils and 259 records of expansive soils. In both soil types, the predominance of this data occurred in the Northeast Region, especially in the state of Pernambuco. Based on climatological, pedological and geological conditions, the application of Artificial Neural Networks (ANN) resulted in interpretative maps. Regarding collapsible soils, the results showed high susceptibility in 27.8%, medium in 3.4% and low in 16.8% of the national territory. The absence of collapsible behavior is equivalent to 49.4%. Regarding expansive soils, high susceptibility was found in 35.9%, medium in 9.8% and low in 3.7%. The absence of expansive behavior represents 48.0%. In both soils, water bodies and urban areas correspond to the percentage of 2.6%. The application of BI technology made it possible to transform the large volume of data into relevant information relevant to climatology, pedology, susceptibilities and geotechnical data. Web applications provide agility, practicality and utility due to the speed of processing, the friendly interface and the option of consulting tools in the preliminary stage of engineering projects. This resulted in easy access to information on susceptibility to collapse and expansion to different locations in the Brazilian territory.
