Sensitivity Analysis of E-B model for Axial Zoned Concrete-Faced Rockfill Dam
Axial zoned concrete-faced rockfill dam (CFRD) divides the dam shell along the dam axis. Through the filling of different modulus materials, the three-dimensional deformation of the dam shell can be reduced, and the extruding rupture of high CFRD and even ultra-high CFRD can be improved. Its mechani...

| description | Axial zoned concrete-faced rockfill dam (CFRD) divides the dam shell along the dam axis. Through the filling of different modulus materials, the three-dimensional deformation of the dam shell can be reduced, and the extruding rupture of high CFRD and even ultra-high CFRD can be improved. Its mechanism and effect are different from those of traditional transverse two-dimensional zoned CFRD. To study the influence of the parameters of the E-B model on the numerical simulation of stress and deformation of the axial zoned CFRD, this paper takes the parameters of the Duncan-Chang E-B model as random variables, takes dam settlement, the deflection of the face slab and axial stress of the face slab as objective functions, and studies the material parameter sensitivity of the axial zoned CFRD through the orthogonal test. The results show that the stress and deformation state is more sensitive to the bulk modulus radix <italic>K</italic><sub>b</sub>, break ratio <italic>R</italic><sub>f</sub>, internal friction angle <italic>φ</italic><sub>0</sub> and the elasticity modulus radix <italic>K</italic>, and less sensitive to the bulk modulus index <italic>m</italic>. |
