EXPERIENCE WITH MATHEMATICAL MODELING IN PROGRAM PLAXIS: DESIGN AND ASSESSMENT OF RETAINING WALLS.

The construction of the highway D47 was needed to ensure connection to the existing road network in Ostrava. These reroutings due to the character of the area consist mainly soil embankment. In cases when it was not possible to implement the classical earth embankment, was used for retaining walls of reinforced soil (system Armovia®). This paper approaches the issue of geotechnical and geodetic monitoring of these structures. There were observed leveling points to the structure, pore pressures in the subsoil of embankment (piezometric measurements), settlement hydrostatic leveling. Interest object is tracked since 2004. Analysis of the behaviour of the structure was supported by mathematical modeling with the Plaxis software. This was also obtained feedback on the suitability of the chosen measurement method and the efficient distribution of observed points on the structure. [ABSTRACT FROM AUTHOR]
