چکیده مقاله
The Mirabad pumped storage project, now under feasibility study stage and predicted as a lower CFR dam and a upper cut & cover dam, is located in a region of high seismicity A seismic hazard analysis was performed to determine the design ground motion parameters for the project The ground motion parameters for the MDL, DBL and CL were obtained from a PSHA whereas the MCL ground motion was derived from a DSHA Among the many faults occurring within the area considered for the analysis, there are four major faults i e Binalud, Neyshabur, North Neyshabur and Fariman , all with a seismic potential of M≥6 9 and a rupture length exceeding 0 5 km, regarded as the most critical ones for the Mirabad dam site The Binalud fault, a WNW ESE striking thrust fault is the one closest to the project site with a distance to the seismogenic rupture surface of only 0 5 km With this fault the medians 50th percentile of the PGA for the MCL are respectively: 0 72g and 0 57g for the Lower Dam site
