First Reservoir’s Impoundment of Plovdivtsi Asphalt-Concrete Core Rockfill Dam
IOP Conference Series: Earth and Environmental ScienceAbstract A two-dimensional explicit FD program FLAC 2D (Itasca Consulting Group Inc., 2011) model was developed to simulate the seepage flow and evaluate the static performance of the Plovdivtsi ACRD dam. Plate load tests conducted on site during construction were modelled in this study to establish the Duncan-Chang parameters.
