Stress-Deformation Properties of High Concrete Face Rockfill Dam in Narrow Valley

摘要：

This is a case study of the stress-deformation properties of high concrete face rock-fill dam (CFRD) constructed in narrow valley using the method of numerical analysis. The arching effect of the valley and the deformation properties between rockfill and abutment and their effects on the stress-deformation properties of CFRD are studied. The creep deforma-tion behaviors of CFRD in narrow valley are also discussed. Results show that the narrow valley has significant arching effect and such CFRD has large tangential slip at perimetric joints but relatively small stress deformation. The slip between dam and abutment and the dam deformation at later stages will have significant impact on dam safety.
