COC811 - Tópicos Especiais em Estruturas de Contenção

Objetivos

Desenvolver conceitos sobre o comportamento e procedimentos de análise de estruturas de contenção, incluindo a técnica de solo reforçado 

 

Ementa (Syllabus)

 

  1. Serão apresentados procedimentos usualmente adotados para análise e projeto desse tipo de estruturas e discutidas suas limitações.
  2. Serão destacadas a influência de diversos fatores (inclinação da face, rigidez da face, resistência na base do muro, tensão induzida pela compactação do material de enchimento e variação da sobrecarga aplicada) no comportamento e desempenho destas sob condições operacionais.
