Indoor flexural fatigue tests are carried out, the results are analyzed and two types of double logarithm fatigue equation under different stress level andequivalent stress level are got. Using the fatigue equation, the fatigue performance of porous concrete and common semi-rigid base materials and cement concrete are compared, the fatigue stress coefficient which is used in the load stress calculation for porous concrete as undersurface of cement concrete pavement and the tensile strength structure coefficient which is used in the flexural stress check for porous concrete as base of asphalt pavement are obtained.

For vortex-liquid phase,the E-J relation could be described according to the Kim-Anderson model:U=U0(1-J/JC).While for vortex-glass phase,the electric field decays verydramatically with decreasing current density,so it is difficult to be observed with theinstrument has limited precision.In the intermediate current region,the E-Jrelations of the both phases could be fitted in terms of a phenomenological model:U=(U0/μ)[μ-1],it was concluded that the sign of μ-value changes fromnegative to positive when the temperature decreases lower than the glass-transitiontemperature Tg,meanwhile,the activation energy U enhances dramatically.Whilein the large current region,Zeldov's logarithmic model was suitable for fitthing theE-J curves of the both phase.Moreover,there was no abrupt change of U or thecharacteristic current density IC.However,the effective radius of vortex line variesremarkably around Tg.

对于涡旋液体相，小电流区的E-J关系可以用计及反跳的Kim-Anderson模型U＝U0(1-J/JC)来描述，而对于涡旋玻璃相，小电流区的电场随电流密度减小而迅速衰减，以致很快脱离了实验测量精度的范围；在中等电流区，两相的E-J关系可以用共同的唯象过渡模型U＝(U0/μ)[μ-1]来拟合，得到在玻璃转变温度Tg两侧μ值由正到负的变化，同时激活能U在Tg以下迅速升高；在较高电流区，两相的E-J关系可以很好的用Zeldov对数模型来描述，拟合结果表明U在Tg两侧的趋势没有明显变化，但是涡旋线的有效半径发生了显著变化。
