Numerical Simulation of Seismic Behavior of Menta Dam, Italy

Abstract

Results of static and dynamic analysis of Menta Dam, Italy, for two pre-selected seismic excitations are presented. Static analysis results include effects of: (a) mechanical and fluid flow through the weathered metamorphic rock foundation, (b) staged construction of the dam, and (c) one-step filling of the reservoir. Dynamic analysis results include effects of: (i) natural vibration characteristics of the dam and foundation, (ii) deconvolutions of the seismic accelerations, and (iii) two seismic excitations. Computer programs used include: FLAC (Fast Lagrangian Analysis of Continua) for the static and dynamic analyses; and SHAKE for the deconvolution analyses. Comments on the results presented are included.
