ABSTRACT
The aim of this article is to present the solutions for the main retaining walls and pavement strengthening, adopted in an industrial warehouse at Quinta do Adarse, in the proximities of the Tagus River right bank, at Alverca, Portugal. The existent cantilever reinforced concrete wall with 300m of length and 6m of maximum height, was strengthened with a cap distribution beam due to excessive deformation. The cap distribution beam was supported by inclined steel struts and founded on micropiles. At the warehouse pavements, some differential settlements were detected around the stiffer structural foundations, mainly due to the water inflow at the pavement earth fill foundation, which required a strengthening solution. Therefore, injections were used to avoid the replacement of the pavement and minimize the impacts on the warehouse’s normal operation.
