14th International Benchmark Workshop on Numerical Analysis of Dams

The Janneh dam is a 162-meter high Roller Compacted Concrete arch-gravity dam under construction in the Nahr Ibrahim Valley of Lebanon. The impounded reservoir will supply water, irrigate agricultural areas and generate hydropower . The dam will serve the Northern areas of Greater Beirut Mount Lebanon . The project site is located in high- seismicity region. The Peak Ground Accelerations are 0.37g and 0.51g respectively for OBE and SEE. Under favorable conditions (shape of the valley, strength of the bedrock, availability of construction materials), the construction of an arch-gravity dam is a more and more interesting alternative. The construction stages are simulated in ABAQUS environment in order to perform both linear and non-linear analyses
