The construction of reinforced concrete diaphragm walls under Encarnación Square comes after the demolition in 1972 of the antique “Mercado de Abastos”. Those works were included into the administrative concession of the Sevilla City Council for the constructions of a new market and underground parking. As the project annex, were made the calculation of the building’s diaphragm walls would contain 3 levels underground, with the conditioning factors to avoid damages on the buildings and roads around. The wall’s execution started on July and finished on November 2002. A total of 8835 m2 and 1840 m2 were built with 80 cm and 100 cm of thickness respectively. Once the containment structure was finished, the anchorages works begin between May and September 2003. This investigation exposes the calculation method used for the walls and anchors and shows the graphic of deformation obtained by inclinometers.
