摘要
利用热粘弹性力学理论和有限元方法 ,以广义Maxwell模型模拟沥青混合料的粘弹特性 ,通过试验研究和理论推导得到其增量型热粘弹性本构关系 ,建立了环境条件下沥青路面的温度应力场有限元计算方法 .
Taking thermalviscoelasticity theory as guide,using the method of test and finite element method,and simulating the viscoelastic property of asphalt mixtures with generalized Maxwell model,this paper launches out a profound study on the thermal stresses in pavements under the environmental conditions.Furthermore,the incremental thermalviscoelastic constitutive relation is obtained from theory derivation and the finite element model of thermalviscoelasticity is built.And a case is given.
