Análise crítica das metodologias gerais de mapeamento geotécnico visando formulação de diretrizes para a cartografia geotécnica no trópico úmido e aplicação na região metropolitana de Belém escala 1:50.000

Abstract

This thesis brings within its scope the critical analysis of the main national and international methodologies of geotechnical cartography (IAEG, Australian, French, EESC-USP, IPT, IG-UFRJ and IG-SP), as well as the classification of a set of rules for the elaboration of geotechnical maps and charts in the Brazilian Humid Tropics. It also presents geotechnical mapping at the scale of 1:50 000, of the Metropolitan Region of Belém, in the State of Pará, comprising the municipalities of Belém, Ananindeua and Marituba. The methodology is based on the above-mentioned cartographic (conventions/ rules), and is presented in the form of eleven cartographic items: a documentary map of the Metropolitan Region of Belém, at a scale of 1:50 000; a documentary map of the central area of Belém, at a scale of 1:10 000; a gradient map; a geological map; a map of unconsolidated materials; a soil use map; a map of institutional areas and conservation units; a map of floodplain and mainland areas; a map of zones of permanent protection of water bodies; a chart of the preferential areas for the exploration of natural construction materials; and a chart of the preferential areas for the installation of sanitary landfills.
