Nonlinear Finite Element Analysis for Stress and Deformation of CFRD
Based on Duncan-Chang’s E-B constitutive material model, the finite element calculating model for a CFRD was established, and has obtained the stress-strain distribution and variety rule at the dam and the face slab in construction period and water store period. The calculation results show that: the stress-deformation behavior of the dam is normal, the deformation values within the acceptable range; the shear failure for the dam is almost impossible; stress concentration and tensile loading on small principal stress was exist on small range of the dam foundation covered by toe slab; the substantially change of water level has great effect on the deformation and camber of the face slabs; the faults structures in dam foundation only has affect the stress distribution of the foundation, but has weak impact of the stress and deformation of the dam body.
