摘要 针对沥青混凝土路面水损害问题,运用轴对称有限元方法分析了不同等级轴载作用下沥青混凝土路面层间孔隙水压力的变化规律。研究结果表明,孔隙水压力将造成路面层间的严重冲蚀,导致沥青与集料过早剥离而诱发水损害,而超载将加速这一进程。 To counter the moisture damage problem of asphalt concrete pavement ,the axis-symmetric finite element method is applied to analyze variety of interbedded pore water pressure of asphalt concrete pavement under different load conditions. The study results show that pore water pressure erodes pavements, induces to strip the asphalt from aggregates so as to arouse moisture damage of asphalt concrete pavement, and overload accelerates this course.
