Abstract This paper investigates the behaviour of the double-curvature Deriner dam, which is in the operation phase and also one of the highest dams in the world. In order to determine the displacements, a geodetic network consisting of twelve reference and seven object points was measured in four periods by means of the Global Navigation Satellite Systems (GNSS) data. The -Criteria method was used to determine the extent of the deformation. The deformation analysis results based on the GNSS measurements revealed significant horizontal and vertical displacements on the object points on the dam crest. Hence, the vertical displacements found based on the GNSS measurements can be considered erroneous, because they are greater than expected. This may be due to the narrow topography of the valley. Another conclusion drawn from the results is that there is a strong relationship between the change in the reservoir water level and horizontal deformations, as can be seen from the horizontal deformation vectors.

监测混凝土大坝的变形：以土耳其阿尔特文 Deriner 大坝为例

摘要 本文研究了处于运营阶段的双曲率德林纳大坝的性能，该大坝是世界上最高的大坝之一。为了确定位移，通过全球导航卫星系统 (GNSS) 数据在四个周期内测量了由 12 个参考点和 7 个目标点组成的大地测量网络。-Criteria 方法用于确定变形的程度。基于 GNSS 测量的变形分析结果揭示了坝顶目标点的显着水平和垂直位移。因此，基于 GNSS 测量发现的垂直位移可能被认为是错误的，因为它们大于预期。这可能是由于山谷地势狭窄。
