Methodology to relieve tensions in buried pipelines in areas of slow land moviment; Metodologia para alivio de tensoes em dutos enterrados em areas sujeitas a movimentacao lenta do solo

Abstract

This paper shows the methodology developed by TRANSPETRO Team of Geotecnia and used to relieve the MERLUZA pipeline tensions. After the problem is detect by usual Systematic Geotechnical Inspections and confirmed by direct and indirect measures, which identify deformations (curve model) caused by strength of land movement, this methodology is apply in this section. In this intervention the standard procedures consist on the following steps: test 'in situ' on the surface of pipeline iron; installation of instruments to measure the relief of tensions; controlled excavation of the ditch; installation of permanent instruments to measure the future new deformations and tensions; and the recomposition of the place with compact land.
