ABSTRACT
The following paper presents a comparison in designing retaining walls according to Eurocode 7, detailing the result differences obtained by each design approach combination for a number of soils each with its own specific parameters. For each calculation the required height of the retaining wall and the surcharge force is considered the same. Using the MDC software, a number of simulations were ran in order to obtain the most economical dimensions of the structure for each type of soil. As results, the quantity of materials, the foot length of the wall and the coefficients for the most unfavorable action (sliding, overturning, limit state) are detailed. The paper concludes with an overview on the most likely design approach and unfavorable action to cause the worst case scenario in designing retaining walls.

Keywords: retaining walls, Eurocode 7, design approach combinations, soil parameters.
