Abstract [en]

A 160 (525 ft) m high asphalt concrete core rockfill dam is developed in an area of very high seismicity in Cetin, Turkey. Topographical constraints of the dam footprint impose a steep outer geometry of the dam, requiring the geotechnical properties of the rockfill to comply with certain minimum limits. Test blasting in a potential quarry and rockfill rolling compaction trials suggest that the tested gneiss/schist rock material to a large extent is weathered and weak. The friction angle of the rockfill is a decisive parameter for both the static and dynamic stability of the dam slopes and especially for the deformation of the dam crest due to strong earthquakes. The suggested rock fill material has therefore undergone detailed testing. To this end, large-scale shear tests with a 1000 mm diameter sample cylinder have been carried out at the Luleå Technical University in Sweden.
