83 EXPANSION PORT TERMINAL Barcarena, Brazil A new expansion project is underway for a private port terminal in northern Brazil. The focal point of the expansion is a robust reinforced concrete pier, spanning approximately 200 m in length and 25 m in width. This upgraded terminal can accommodate the mooring of two large cargo vessels, including Panamax ships up to 250 m long and fertilizer import vessels up to 215 m long. Given the significant disparity in levels between the riverbed and the pier slab, deep foundations were crucial, reaching depths of approximately 32 m. To mitigate displacements caused by the vessels, inclined pile foundations proved to be the optimal solution. These 1.1 m diameter piles were constructed using steelwork filled with reinforced concrete. The pier construction process involves two stages. The first stage entails the installation of prefabricated concrete beams in a “U” shape, with spans ranging from 6 m to 9 m. In the second stage, “T” shape beams are introduced. At the lateral ends of the pier, where vessels dock, vertical slabs with buttresses were added to handle the substantial energy exerted by the vessels, reaching up to 1500 kN.m of absorbed energy and a horizontal reaction of 1400 kN.
