ABSTRACT

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.
