| Abstract: | Duncan-Chang model can better reflect the soil of the nonlinear behavior,the concept of clear,easy to understand,in geotechnical engineering and underground works in the numerical analysis is widely used.In a specific numerical calculation,to use the specific parameters.Some literature,books and general information is given in the sand,clay parameters of Duncan-Chang model.By conventional triaxial test,get the sand Duncan on a different size model parameters a,b value of the impact. |
| Keywords: | sand conventional triaxial experiment mechanical properties Duncan-Chang model |
