| Zusammenfassung |
| Sacele reservoir is locate on the river Tàrlung, about 3 Km upstream from Sacele and about 12 Km from Brasov (Romania). It represents the main drinking water source for Brasov. The Sacele reservoir is recognized as a dam of exceptional importance and therefore it requires special surveillance.
In the East side of the basin, in proximity of the barrage, the slope shows evidences of instability; for this reason stabilization works, mainly consisting in re-profiling the slope, and drainage installation, has been conducted without success.
This study, financed by the World Bank, aims to provide important information for the estabilishment of an authomatic monitoring system able to reduce the existing risk.
Conducted studies includes:
- analysis of existing informations
- data acquisition by mean of field survey (geodetical and gelogical) and in situ investigation (boreholes, geophisical, sample test)
- developement of GIS based geological model
- developement of landslide models based on FLAC and FLAC3D
Finally the model results leading to the identification of the triggering factors are discussed.
The conducted work is a comprehensive study (from data to models) that highligth some interesting conclusions showing how the "stabilization" works increased total displacements and shear strain, and produced a new deeper cinematic. |
