STATIC ANALYSIS OF CONCRETE FACED ROCKFILL DAMS USING NONLINEAR MATERIAL BEHAVIOR

Analysis results of a typical concrete faced rockfill dam under self-weight and water pressure loads using nonlinear constitutive model for rockfill material and considering step by step construction stages is presented. The analysis is based on a computer program developed using main body of ANSYS program and a subroutine is written to add the critical state behavior model to the software. Two common problems are solved for evaluation of the software and then a typical CFR dam is modeled and analyzed. Results of analysis show the nature of plastic deformation distribution in the dam body and effect of water level variation on concrete face slab response.
