| 摘 要： | 为探求交通流荷载下高速公路沥青路面的使用寿命,采用层状体系理论,建立ANSYS 3-D有限元粘弹性路面结构模型;根据损伤力学理论研究单轴载通过时由沥青层底部的最大拉伸应变造成的路面破坏;再由Miner's线性累积损伤理论得到在实际车流荷载作用下沥青路面发生一定破坏程度时的使用寿命.计算结果表明,研究路段的沥青破坏路面等...

| Abstract: | To study the service life of asphalt pavement under traffic loads,a 3-D finite element analysis(FEA) visco-elastic road model was established with the layered theory and ANSYS software.The fatigue damage was calculated with the maximum horizontal tensile strain of bottom asphalt layer based on the fatigue fracture mechanics when a single axis load went across.Then,the fatigue life was obtained after the fatigue damage occurred in some degree by the Miner's linear cumulative damage rule.The results showed th... |
