摘要
根据损伤力学的相关理论,用循环耗散能定义为沥青混合料的损伤变量,据此根据疲劳试验推导出了损伤函数、损伤演化方程,并验证了该损伤模型与经典Miner线性损伤模型的关系,同时说明了该模型的可行性。
According to the corresponding theories of the damage mechanics, the author defines the circulation dissipated energy as the damage variable of the asphalt mixture, according to the figure test derives the damage function and damage evolution equation, and checks the relationship between this damage model and classical Miner linear damage model, describes the feasibility of this model at the same time.
