| 摘 要： | 采用有限元方法,分析了旧沥青路面裂缝对白色罩面层受力的影响,得到了板底荷载和温度最大耦合应力随加铺层厚度和模量等参数变化的规律。结果表明:旧沥青路面横向裂缝位于加铺水泥混凝土板板中时,板底荷载应力、温度应力及二者耦合应力均为最大,且随加铺水泥混凝土板模量增加而增大,随水泥加铺层厚度的增加而减少。

| Abstract: | The influence of old asphalt pavement crack on white overlay stress is analyzed using finite element method,from which,the rule of the maximum load and temperature coupling stress under slab varying with the changes of overlay thickness and modulus parameters has been obtained.The result shows that when transverse crack of old asphalt pavement is at the middle of overlaid cement concrete slab,load stress,temperature stress and their coupling stress are the maximum.In addition,they will increase when overlai... |
