Chaglla CFRD-Main Design Features
(0) Chaglla Dam, located in Peru, is part of the Chaglla Powerplant and will have an installed capacity of 450 MW.The Chaglla CFRD is 211.0 m high, will have a volume of 8 150 000 m3 and presents a set of particularities, such as the material zoning, a narrow valley with a low shape factor (A/H2), around 1.50, and a steep right abutment, with average inclination of 70°, that conditioned important design features.The dam design demanded rigorous solutions based on the state of the art adapted to the site conditions in order to guarantee the dam proper performance.The dam zoning arrangement took into account the valley shape, the use of natural granular materials, besides the processed ones from quarries or excavations, configuring a gradual material stiffness zoning.Due to the right abutment topography, an unconventional plinth was designed, shifting at El.1 080.0 from a horizontal to a vertical geometry, which enabled the reduction of the excavation.In addition to the adopted design criteria, this paper presents the results of the stress and deformation analyses performed by a three-dimensional finite element model and its contribution for the dam design as well as the aspects related to the dam construction planning.
