Saber qual Ã© o empreendimento mais racional para cada necessidade geotÃ©cnica de uma cidade Ã© sempre um desafio. PolÃªmicas sobre decisÃµes nesse sentido sÃ£o muitas vezes baseadas na falta de conhecimento. Com o objetivo de auxiliar nesta questÃ£o, a ITA (International Tunneling Association) publicou, na 42Â° ediÃ§Ã£o do ITA@News, um guia sobre tÃºneis imersos, produzido pelo ITA Working Group 11 for Immersed and Floating Tunnels. QuestÃµes como a definiÃ§Ã£o correta de tÃºnel imerso e locais apropriados para a construÃ§Ã£o deste tipo de travessia sÃ£o analisados no Guia, que tem como princÃpio responder Ã questÃ£o âo que Ã© preciso saber e documentar para planejar, construir e operar um tÃºnel imersoâ. O intuito da entidade na publicaÃ§Ã£o Ã© ampliar a compreensÃ£o do tema, que estÃ¡ em pauta no Brasil com o caso da travessia Santos-GuarujÃ¡. Leia a Ãntegra.
