Abstract

Cataclastic structure rock mass is very common in superficial geological body whose stress-strain law closely concerned with the structural plane. Based on one-dimensional constitutive model presented by Professor GZ-Sun for cataclastic structure rock mass, a three-dimensional constitutive model is established in the paper, and then the model is embedded into FLAC3D by using its user defined model (UDM) function. Taking a typical gently inclined bedding slope for example, three-dimensional numerical simulation is made by using this new constitutive model, and the results can well indicate the stress-strain characteristics of cataclastic structure rock mass.
