This paper studied the damage , fracture , fatigue and water fracture mechanics of Portland cement concrete pavement with the twin shear theory, minimum energy dissipation theory and fractal theory combination. The main research contents and results of the thesis are as follows:1 .
本文采用双剪理论、最小耗能原理和分形理论研究混凝土路面的损伤、断裂、疲劳和水破坏机理,并应用这些研究结果于水泥混凝土路面结构设计及维修分析,主要研究内容及结果如下: (1)采用双剪理论和最小耗能原理研究混凝土路面损伤直到断裂破坏的过程,首次采用双剪理论与最小耗能原理建立混凝土路面双剪强度准则,导出破坏准则的参数b值,证明目前采用的混凝土路面破坏准则可行,建立考虑损伤的混凝土路面应力分析方法。
