The bridge superstructure consists of two continuous, concrete decks, parallel and independent, with the following spans: 65 + 3 \uf0b4 115 + 150 + 100m, thus the 6 spans have a total length of 730m.<\/p>\n
Each deck consists of a single-celled box girder in prestressed concrete and were cast \u201cin situ\u201d by the balanced cantilever method in 5.0m segments. <\/p>\n
The box girders have webs and upper slab of constant thickness. The bottom slab thickness decreases continuously of from the piers to the center of the spans.<\/p>\n
The piers are in reinforced concrete and are formed by a tubular cross-section, constant along the full height.
\nThe piers located in the riverbed rest on massive pile caps. The remaining piers have direct foundations on altered schist formations.<\/p>\n
The construction lasted 18 months and was concluded in August 2010.<\/p>\n","protected":false},"featured_media":0,"template":"","categories":[],"tags":[],"class_list":["post-5196","projectos","type-projectos","status-publish","hentry"],"acf":{"enquadramento":"r2","imagem_hp_destaque":{"ID":3958,"id":3958,"title":"P272_Projeto_855x320","filename":"P272_Projeto_855x320.jpg","filesize":40698,"url":"https:\/\/www.arito.com.pt\/wp-content\/uploads\/2021\/06\/P272_Projeto_855x320.jpg","link":"https:\/\/www.arito.com.pt\/en\/projectos\/ponte-sobre-o-rio-douro\/p272_projeto_855x320\/","alt":"","author":"12","description":"","caption":"","name":"p272_projeto_855x320","status":"inherit","uploaded_to":3957,"date":"2021-06-28
