| Zusammenfassung |
| Monitoring deformation pattern of dams is often one of the most effective
ways to understand their safety status. The main objective of the study is
to find the extent to which rising reservoir level affects the mechanism of
deformation of The Yamula Dam under certain change in the reservoir level
conditions during to the first filling period. Three different deformation
analysis techniques, namely static, kinematic and dynamic, were used to
analyze four geodetic monitoring records consisting of vertical
displacements of nine object points established on the Dam and six reference
points surrounding of it, to see whether the rising reservoir level have a
role in the vertical deformations during the first filling period. The
largest vertical displacements were in the middle of the dam. There is an
apparent linear relationship between the dam subsidence and the reservoir
level. A dynamic deformation model was developed to model this situation.
The model infers a causative relationship between the reservoir level and
the dam deformations. The analysis of the results determines the degree of
the correlation between the change in the reservoir level and the observed
structural deformation of the dam. |
