The first prototype reinforced soil bridge pier was constructed by means of preloaded and prestressed (PLPS) reinforced soil method, which aims at substantially increasing the stiffness of a geosynthetic-reinforced soil embankment by vertical preloading and prestressing. After the usage for a period of three and half years, cyclic and creep loading tests in the vertical direction were performed on this pier before its destruction work. In this paper, the deformation characteristics of the PLPS structures are discussed based on behaviours of the pier during the construction, the service period, and the final loading tests.
