Support to urban planning from geotechnical map built on SPT data at Porto Velho-RO, Brazil

摘要

The present work, aims to support the municipal county planning with an instrument of geotechnical analyses built from the collection of Standard Penetration Tests performed along the urban site for various purposes. Once they were collected, the geotechnical information was organized using computational spreadsheet, including its geographical coordinate's location. Parameters concerned for urban planning, such as top soil characteristics of permeability, texture, resistance and water table depth, were grouped and analyzed through SURFER~? software that was also used to generate the thematic maps. The city municipal planning law is currently been revised for definition of urban zoning occupation and sanitation priorities for sewage works. This study supported the urban land use director plan by presenting the different soil geotechnical characteristics.
