| 摘 要： | 针对沥青路面水损害问题，运用轴对称有限元方法分析了标准轴栽作用下沥青路面层内孔隙水压力的变化规律及其对沥青路面结构应力状态的不利影响。研究结果表明，孔隙水压力致使沥青与集料剥离，并引起沥青路面内部开裂，从而造成沥青路面过早破坏。

| Abstract: | This paper is aiming specifically at the moisture damage problem of asphalt pavement, and the axis - symmetric finite element method is performed to analyze variety of pore water pressure in asphalt pavement and its negative effects on stress state of asphalt pavement. The study results revealed that the pore water pressure induces stripping of the asphalt from aggregate and makes asphalt pavement cracked inside; which results in premature failure of asphalt pavement. |
