基于断裂力学的水泥混凝土路面裂缝成因分析

Causes Analysis of Cracks in Cement Concrete Pavement Based on Fracture Mechanics

水泥混凝土是典型的带裂缝构件,应用断裂力学的原理分析水泥混凝土路面初期、中期、后期三个破坏阶段之间的关系,确定每个阶段混凝土路面裂缝形成的根本原因,可为水泥混凝土路面抗裂研究和处治提供科学依据。

Cement concrete is typical component with cracks.Based on the principle of fracture mechanics,the relationships between early,middle and later damage stages of cement concrete pave-ment are analyzed to make sure the basic cause of cement concrete pavement crack in each stage,which can provide reference for studying and controlling the cracks in cement concrete pavement.
