| 摘 要： | 以高等级公路半刚性基层沥青路面的U形开裂损坏为研究对象,采用有限元软件ABAQUS建立力学模型,对引起U形开裂的因素--层间接触条件和超载进行力学分析,并对其影响显著性进行方差分析.经过计算分析得知:层间接触条件和超载对沥青路面U形开裂的产生均有显著性影响,且面层层间接触条件要远远大于基面层间接触条件对其产生的影响.若...

| Abstract: | The U-shaped cracking in semi-rigid base asphalt pavement of high-grade highway was studied.A mechanical model was built by using finite element software ABAQUS to analyze the effect of interface contact condition and over loading on U-shaped cracking.Significance of influencing factors was also discussed by variance analysis.The analytic results show that the generation and development of U-shaped cracking is significantly influenced by interface contact condition and over loading,and the contact condition... |
