摘要
基于断裂力学理论,结合热力学原理,分析了混凝土冻融破坏的原理,并基于Paris公式,在冻融破坏等效的基础上,推导出了混凝土经冻融循环作用后剩余寿命预测公式,以期为广大研究者提供借鉴.
Based on the fracture mechanics theory, combined with thermodynamics principle, the principle of freeze-thaw damage to concrete is analyzed; on account of Paris formula, the residual life prediction formula after the freeze-thaw cycle is derived on the basis of equivalent to the freeze-thaw damage concrete, in order to provide a reference for the researchers.
