Since the raw materials are taken from volcanic rocks, they are inherently chemically stable and thermally stable.
Specifically, the combination of the direction angles of the reinforcing materials in the solid constants of Solid65 should be (90,0), (0,0), (0,90), and the volume ratios ρx, ρy, ρz in the three directions should be One-third of the volume rate [3-5], as shown in Figure 1.

According to the statistical material from China Commission on Large Dams[1], to the end of 2005, in the 4860 DAMS which above 30 metres that has been built or under construction, rock-fill dam accounted for 59% .
In view of the construction period, the clay core wall is in the unsaturated state, and has a certain degree of consolidation, so suggest to use unsaturated core wall material consolidated undrained triaxial tests determine the parameters.
The parameters of unsaturated mixed gravel clay core wall and dam shell rock-fill materials of Shuangjiangkou dam for Duncan model was shown in table 1.

Despite that the formula is only an approximate expression, once the S-N curve of the material is known, can we easily estimate the fatigue life when the material is under the complicated loading based on the formula of the linear accumulative damage theory.
When the stress that the material endures is higher than the fatigue limit stress, every cycle can make the material be a certain damage.
