| 摘 要： | 文章利用有限元软件Ansys对不同车速、轮胎接地应力、结构层厚度及模量情况下的水泥稳定基层进行了疲劳寿命影响分析。结果表明：（1）随着车速的增大,基层疲劳寿命不断增大;（2）随着轮胎接地应力的增大,基层疲劳寿命逐渐减小;（3）基层疲劳寿命随基层和面层厚度的增大均呈增大趋势;（4）基层疲劳寿命随基层模量的增大而不断增大,随面层模量的增大而逐渐减小。

| Abstract: | The article performs fatigue life influence analysis on cement stabilized base under different speed,tire stress,structure layer thickness and model condition by using finite ele-ment software ANSYS.The result shows:1.As speed increases,the fatigue life increases;2.Fatigue life decreases as tire stress increases;3.Fatigue life increases as base and layer thickness increases;4.Fatigue life increases as base modulus increases,but decreases as layer modulus decreases. |
