| 摘 要： | 引入粘弹性理论，推导了温度荷载作用下的二维粘弹性有限元格式，并用Burgers模型模拟沥青混合料的粘弹特性，根据推导出的公式，编制了有限元程序，计算在持续大幅降温条件下沥青路面结构的温度应力场。

| Abstract: | Viscoelasticity theory is used to derive two-dimensional space finite-element formulas when temperature load acts on pavement. Bu rgers model is applied to simulate the viscoelasticity property of asphalt mixture. A finite-element procedure based on the formulas which have been derived is carried out to calculate the stress in pavement when sharp continuous fall in temperature occurs. |
