Abstract

Bakun Concrete Faced Rockfill Dam (CFRD) become second highest CFRD in the world is analyzed for its structural response due to its self-weight by using Finite Element Method. Non-linear Duncan-Chang hyperbolic Model is used to study the structural response of the dam in respect to the deformation and stresses of Main dam of Bakun's CFRD project. The model was modeled as 2-D and analyzed as plain strain problem by using isoparametric elements, interface elements and infinite elements to represent the entire element been meshed. Dead-Birth-Ghost element technique was used to simulate sequences of construction of the dam. The comparison of rigid and flexible foundation on the behaviour of the dam was discussed. The maximum horizontal and vertical displacement of the cross section at different stages of construction was founded and the distribution of them were discussed in form of graphs and contours.
