Abstract
The paper presents the development of a decision support system for the management of geotechnical and environmental risks in oil pipelines using a geographical information system. The system covers a 48.5 km long section of the São Paulo to Brasília (OSBRA) oil pipeline, which crosses three municipalities in the northeast region of the São Paulo state (Brazil) and represents an area of 205.8 km2. The spatial database was created using geo-processing procedures, surface and intrusive investigations and geotechnical reports. The risk assessment was based mainly on qualitative models (relative numeric weights and multicriteria decision analysis) and considered pluvial erosion, slope movements, soil corrosion and third party activities. The maps were produced at a scale of 1:10,000.
Résumé
L’article présente le développement d’un outil de décision pour la gestion de risques géotechniques et environnementaux concernant des oléoducs sur la base de Systèmes d’Information Géographique (SIG). L’outil de décision concerne une section de 48,5 km de longueur de l’oléoduc allant de Sao Paulo à Brasilia (OSBRA), traversant trois municipalités dans le nord-est de l’état de Sao Paulo (Brésil) et porte sur une surface de 205,8 km2. La base de données spatiales a été créée à partir du traitement de données géologiques, de reconnaissances de surface et en forage et de rapports géotechniques. L’évaluation du risque a été basée principalement sur des modèles qualitatifs (analyse multicritère avec pondération numérique des paramètres) et en considérant l’érosion pluviale, les mouvements de terrain, l’altération des sols et les activités anthropiques. Les cartes ont été produites à l’échelle du 1/10,000.
