Along with the development of computing science, rock core discing numerical simulation more and more being at a premium.
The main cause of rock mass stability is destroy stress being larger than resistance, the former is resulted from stress environment, the latter depends on the strength parameters of material strength.

To a certain extent, the existing results reveal that 2D problem of fracture mechanism of brittle material like rock is significantly different from 3D problem.
To uncover the bottom, Dougill introduced damage mechanics into study of the meso-crack development in rock and concrete in 1976[7], and the study of material damage at meso-level has developed rapidly.
This double-layer structure can not only reduce the effect of chamber material on CT scanning results, but also adjust temperature through injection water between the two layers.
The parameters of the material are: density 2.24KN/m3, uniaxial compressive strength 14.72 MPa, Young's modulus 6.86×103MPa, cohesion 1.75MPa, inner frictional angle of 51.5º.

Cellulose fiber modified bituminous mixtures was a composite material that was obtained by adding fibers which could reinforce the asphalt mastic and asphalt mixture’s pavement performance.
Materials and methods Materials.
Through comparing the differences of modified asphalts’ performance, that whether the composite of diatomite and cellulose had effects on performance of the modified asphalt was found, and if it was necessary to manufacture composite materials.
