摘要

The Kemah arch dam is situated in Turkey close to the Eurasian Seismic Zone, where the peak ground acceleration of a 2 500-year earthquake reaches to a value of 0.70g. In this paper, the planning and design of the arch dam are reported besides presentation of main features of the project. Based on the results of geological and geotechnical investigation including the karstic foundation, shape of the arch dam was optimized using the time-history approach to cope with the extraordinary seismic loading, and the stresses in the arch dam and foundation were analysed in each time step. Based on the determined tensile and compressive stresses, the required concrete classes were accordingly defined.
