Abstract
Port constructions (quay and dike) require an enormous consumption of materials, in particular concrete and its components, as well as sand, hence the need to develop alternative solutions by using port dredging sand, which is evaluated by thousands of tons by its use in the concrete that forms the blocks of quay walls. After having demonstrated in a previous work the possibility of using the dredged sand from the port of Agadir in concrete formulations, the present work consists to show the possibility of using the dredged sand from the port of Agadir in concrete formulations that can be used in the construction of quay wall blocks, by studying the stability of a quay wall at −18 mZH made from concrete blocks derived from a concrete formulation based on the dredged sand, more specifically 50% of the sand used in the formulation is a dredging sand extracted from the port of Agadir, the quay wall stability study will consist of a deep analytical and detailed study of the sliding stability, the overturning and the bearing capacity of the foundation, taking into account the different calculation limit states, the structure of the quay wall studied is the quay wall of the port of Tangier Med II located in the north of Morocco. The eventual use of dredged sand in the concrete of the quay wall will provide enormous gains in the quantities of sand and therefore allow less consumption of construction materials, and will also play a more important role in the preservation of the marine environment by avoiding the dumping of dredged materials, which has a negative impact on the marine fauna and flora.
