STRUCTURAL BEHAVIOR OF A REINFORCED CONCRETE ARCH CULVERT. PHASE 3. CEDAR CREEK. SECTION VIII: DETERMINATION OF ARCH BARRELL DISPLACEMENT FIELD

Photogrammetric methods were employed to assess the displacement field for fifteen points along the intrados of a 22-ft (6.7 m) arch culvert buried under 191 ft (58 m) of embankment at Cedar Creek. Photos were taken on astronomical glass plates from two positions by a stereometric camera, and a comparator was used to establish coordinates. Progressive displacements were calculated at intervals of embankment construction. Coordinate planes established in the photogrammetric process differed from those used in the neutral point and finite element analyses so that correlations of observed and quasi-theoretical results required application of a series of transformations to the former. Section VIII of the report describes the transformation algorithm and provides a program listing and plots of transformed displacements.
