The accuracy of strain tensor determined in the landslide areas
Geodetic surveys, performed serially in the area subject to deformations, allow to determine deformation rates, of which, for most building structures, horizontal strains appear to be the most important ones. There are horizontal tensile and compressive strains. Tensile strains of land cause the greatest damage to residential buildings, resulting in hairline and larger cracks, or even construction disasters in extreme cases. Depending on the adopted surveying method, it is possible to determine the values of strains more or less accurately. For the strains with small values it is necessary to determine the length directly (from the total station measurement), whereas for the strains with large values it is possible to use the GPS measurement results. The article presents the surveying method and the measurement results of landslide fragments deformation. Geodetic points were stabilized in the form of a control network called a rosette. Measurements of the rosette were performed and, on their basis, horizontal strains were calculated for the directions of the stabilized sides. The further stage included determining surface strain tensor components, from which it is possible to determine the direction and the values of the occurring extreme strain.
