基于一维模型的沥青混凝土的开裂温度分析

Crack Analysis for Asphalt Concrete Based on One- Dimension Model

文中分别采用公式法和有限元法,对不同环境条件下的沥青混凝土杆累积温度应力计算,通过计算说明了有限元法的有效性。接着考虑沥青混凝土因降温导致的非均匀性后,对一维沥青混凝土杆的开裂温度进行了预测。

By adopting formula method and Limited Unit method to calculate the accumulative thermostress for asphalt concrete in different surrounding,this paper explains the validity of Limited Unit method. Furthermore,by considering the non-uniformity lead by temperature decrease,the authors predict the crack temperature for one-dimension asphalt concrete.
