Abstract
This paper presents an investigation of the seismic behavior of the Alpamarca tailings dam which is being raised from elevation 4603 m to 4670 m above the sea level in a region of high seismic activity in Peru. A seismic hazard assessment was carried out taking into account the attenuation law recommended for Peru’s geology and the design earthquake was generated through a spectra matching method. The seismic responses of the dam were computed using FLAC 2D software and the results are presented in terms of accelerations and permanent displacements. In order to observe the influence of the duration of the earthquake, the results computed with the total record of accelerations (218 s) were compared with those determined using a significant duration D5−95 = 99.36 s.
