摘　　要：针对传统的把行驶车辆看作静载荷对公路的影响的研究的不足,研究了黏弹性沥青路面在行驶车辆荷载作用下动力响应的数值模拟,分析了移动车辆作用下路面三向应变动力响应规律。最后同应变现场实测结果进行了对比分析。结果表明能较好地模拟实际行驶车辆载荷作用下沥青路面的力学响应。For the lack of the traditional vehicles traveling is thought as the static loads on the highway. The numerical simulation of the dynamic response for the viscoelastic asphalt pavement under the moving vehicles loads is studied. The three-way strain dynamic response under the moving vehicle is analyzed. Finally, the method is compared with the results of the strain field measurement. The results show that the method can actually be used to simulated the mechanical response of asphalt pavement under the moving vehicles loads.
