EUROCODE 7 is currently the basic document defining the principles of geotechnical designing in Poland. Contrary to Polish Standards, it focuses primarily on the observational method of designing and site monitoring, or in a broader sense, supervision and control.
One of the method of such monitoring applied by AARSLEFF is the measurements of displacements of retaining structures, including inclinometer measurements of deformations of sheet pile walls and geodetic measurements of the horizontal displacements of their crown in selected locations. The results are then subject to analysis in order to verify the correctness of assumptions made for design calculations and they are also used for the assessment of possible hazards occurring during work execution or/and usage of the structure. Firma Aarsleff performs the measurements of displacements of retaining structures for all the justified cases or in accordance with design requirements.
