Results of analysis show that Generalized Paris Law can consider the complex crack propagation in the material of the pavement structure. The fatigue life of the pavement increases with increasing thickness of surface layer in a power function. Use of a thicker surface layer may extend the service life of the asphalt pavement. The fatigue life increases with decreasing modulus of surface layer in a power function with a negative exponent. However, since reduced modulus would scarify the structural strength and might cause rutting-related distress, caution should be taken when using low modulus materials for improving fatigue performance of asphalt pavements. The fatigue life increases with increasing modulus of base material in a power function. However, the fatigue life can not infinitely increases with increasing modulus of the base.

计算与分析表明:广义Paris公式可以考虑沥青路面结构内材料复杂的裂缝扩展:沥青面层的疲劳寿命随着面层厚度的增加以幂函数的形式增加,适当增加沥青面层厚度可以提高路面的使用寿命;沥青面层的疲劳寿命随着面层材料模量的降低以负指数的幂函数形式增加;由于材料模量的降低将牺牲路面的整体强度并可能引起路面车辙类损坏,以此提高疲劳寿命的方法应慎重对待;沥青面层的疲劳寿命随着基层材料模量的增加呈幂函数的形式增加,但由疲劳方程可以看出,寿命并不是随基层材料模量的增加而无限的增加,疲劳曲线在经过一个上升段后,逐渐趋于一个常数值,这说明,这时基层模量对寿命已不作关键性贡献;随着底基层厚度的增加,面层的疲劳寿命近似地呈线性函数增加,但效果并不很明显。

By measuring the residual stresses of the cylinder of a cement ball mill in four cases,and the fatique crack spreading for the thermal treatment and the un thermal treatment test samples,the results showed that the heat treatment sample reduced the residual stress,enhanced the fatique strength and lowered the crack spreading speed.

对球磨机筒体的4种情况的焊件进行残余应力测试,并对进行热处理和未进行热处理的试件做疲劳试验及疲劳裂纹扩展测试。试验结果表明:经过热处理的试件,残余应力降低,疲劳强度提高,裂纹扩展速率降低,结构抗疲劳性能增强。不过从工程应用角度看,对于板厚为20~25mm的球磨机筒体而言,不进行焊后热处理也能保证足够的疲劳强度
