PROBLEM TO BE SOLVED: To provide a dam construction survey photographing method suitable for highly accurately photographing and surveying a rock adhesive surface at low cost.SOLUTION: Right bank first and second reference points 501a and 501b are set in a region 550 to be photographed including a bedrock surface after drilling in a preset drilling range of a surface protection member that covers the bedrock surface by using the upper corners of two molds 301R and 302R installed at positions opposed to the bedrock surface among molds installed on the upstream side and the downstream side of a dam bank body. In addition, a third reference point 501c is set at a roughly intermediate point between the reference points 501a and 501b and at a prescribed height position on the bedrock surface. A plurality of images of the region 550 to be photographed after the setting of the reference points are photographed by a digital camera DC from a plurality of different photographing positions on the ground or the existing part of the dam bank body, the plurality of images taken from each of the photographing positions, so that parts of the photographing region can overlap among the plurality of adjacent photographed images at photographing positions.SELECTED DRAWING: Figure 6
