Análise e aplicação da IPA-08 do DNIT visando o controle dos processos de instabilização em taludes de corte rodoviários : o caso da duplicação da rodovia BR-163/364/MT

Abstract

The highways are an important tool for the development of the State of Mato Grosso, the most widely used modal to make the production flow logistics and makes the interconnection between the municipalities. The growth of the State of Mato Grosso above the national average generated the need for a large demand for infrastructure, and in particular for adjustments and improvements in the road system. Currently, the Government tries to minimize this situation through implementation of various road works to improve the trafficability and consequently structure their transport logistics. In parallel, this choice by road transport entails significant environmental impacts although the Road Engineering has advanced with regard to construction technology and the concept of environmental preservation. Most road works during their execution phase, not of a rigor and an appropriate methodology to minimize and control the impacts generated primarily to surface water resources ephemeral, intermittent and perennial directly influenced by the construction. Studies on the EIA / RIMA provided for in Article 10 of Law 6938/81 of the National Environmental Policy aiming Environmental Licensing are extremely comprehensive and generic and does not constitute as a proper tool for the proper environmental monitoring of surface water resources during executive these highway. Given this reality, this research has the objective to subsidize methodological procedures in order to anlyze and apply the Instruction of Environmental Protection (IPA-08) in order to serveas a technical tool for the evaluation of environmental impacts on cutting slopes present on the road in construction and caused by changes in the physical environment and in particular in the processes of dynamic surface, generated in the area of direct influence (AID). Therefore, it was adopted as the study area belonging to a segment duplication of BR-163/364 / MT - Rosario Oeste Posto Gil for the purpose of monitor and inspect the area bounded on the impacts to evaluate the performance of the road stretch in study. In this work results are presented as the delimitation of the study area, its subdivision and geotechnical characterization, the characterization and presentation of instability in cutting slopes as well as an analysis and proposed application of the IPA-08 as a form of preventive and corrective control.
