The parameters of materials and the model structure are assumed as following[2][3]： a）Materials in each pavement structural layer is homogeneous, isotropic, and linearly elastic, which means Hooke Law applies.
c）Contacts between any two layers are entirely continuous, and the effect of the pavement materials’ weights are ignored.
A geotechnical fabrics and a geogrid with a mesh size of 1.27cm×1.27cm were used as reinforced materials in the test.

For anisotropic materials, a larger value of plastic strain ratio (r-value) means that the material possesses much higher anti-thinning capability and its drawing formability is better.

For civil engineering structure, especially for high-rise building with concrete as main material, the change of modal frequency sensitivity to the local damage is very low [2], and modal measurement accuracy cannot be guaranteed, the modal dynamic damage index based on frequency, mode of vibration loss its function and unsuitable for local structural damage detection [3].
