A Usina hidrel\u00e9trica Henry Borden, situada ao p\u00e9 da serra do mar possui duas centrais de gera\u00e7\u00e3o de energia, chamadas de externa e subterr\u00e2nea. A usina subterr\u00e2nea foi constru\u00edda dentro da rocha, por motivos de seguran\u00e7a contra ataques a\u00e9reos. Na \u00e9poca de sua constru\u00e7\u00e3o, a rocha fora escavada por meio de utiliza\u00e7\u00e3o de explosivos, o que causou fissuras nas camadas superficiais, as quais aumentaram com o passar do tempo e ocasionaram quedas de blocos na entrada do t\u00fanel de acesso, que \u00e9 a \u00fanica forma de se entrar ou sair das depend\u00eancias da usina<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n

Por se tratar de um grande trecho de instabilidade superficial, situado no p\u00e9 da serra do mar, a melhor op\u00e7\u00e3o para a prote\u00e7\u00e3o das instala\u00e7es foi a instala\u00e7\u00e3o de uma barreira din\u00e2mica contra queda de rochas logo acima da entrada do t\u00fanel. Esta barreira fora dimensionada considerando-se um bloco de 2m\u00b3 de volume, similar a um bloco que j\u00e1 havia ca\u00eddo no ano de 2013. Durante a instala\u00e7\u00e3o da barreira muitos desafios foram superados, como a determina\u00e7\u00e3o do melhor posicionamento da barreira e a adequa\u00e7\u00e3o de sua geometria para atender desn\u00edveis maiores que os especificados no manual de instala\u00e7\u00e3o.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>","protected":false},"excerpt":{"rendered":"
