反射裂缝路面体在变温作用下的静态效应

Static Effect of Reflect Crack under the Action of Temperature Variation

本文采用平面应变有限单元法分析温度变化对基层含有初始反射裂缝路面体的静态效应。鉴于沥青混合料受温度的影响比较大 ,故分析时考虑了温度变化和沥青混合料劲度模量的耦合效应 ,从而使结果更符合实际。

The paper adopted the plan stress finite element method to analyze the static effect of substratum contained with prmary reflect crack. The paper considered change of temperature and the coupling effect of asphalt mixture stiffness modulus when the analysis, because temperature influence mixture.
