| Authors: | Guo Jianyang Huang Shengsheng Yu Xiaosheng |
| Abstract: | Based on the large-scale triaxial experimental resulte, some troublenesses in the E-μ model for big granular media widely used in our country are analysed . It is indicated that the relationship used in the model (σ1-σ3)f = R (σ1-σ3)u l is unnecessary and the semilogarithmic relationship between uf and σ3 is not unique. In order to inprove this model, a more convenient formula is suggested. |
