PHOTOGRAMMETRIC MEASUREMENT OF DEFORMATION IN RETAINING WALLS AND ENGINEERING STRUCTURES

VERFAHREN ZUR PHOTOGRAMMETRISCHEN DEFORMATIONSMESSUNG BEI STUETZMAUERN UND KUNSTBAUWERKEN IM STRASSENBAU (PROJEKTSTUDIE)

THE STRESSES AND DEFORMATIONS WHICH OCCUR IN RETAINING WALLS AND SIMILAR STRUCTURES, UP TO FINAL SETTLEMENT OR RESTING OF THE SUBSOIL, ARE TO BE EXAMINED BY SPECIAL MEASURING METHODS, DEFINED, AND MADE AVAILABLE AS INFORMATION TO CONTRACTORS. A PHOTOGRAMMETRIC METHOD OF MEASURING THE DEFORMATION OF RETAINING WALLS IS TO BE DEVELOPED WHICH PERMITS ACCURATE MEASUREMENTS ON DEFINED STRUCTURAL SURFACES AS PART OF THE OBSERVATION OF ENGINEERING STRUCTURES. THE PHOTOGRAPHS TAKEN ARE TO BE STORED ON A COMPUTER TO PROVIDE DOCUMENTATION.
