亚临界扩展的显著特征要求至少两个控制参数来完整地表述混凝土中裂缝的扩展。基于监测值对裂纹尖端张开位移（CTOD）的基本定义进行了修正。
The distinct characteristic of subcritical propagation requires at least two control parameters to completely express expansion of cracks in the concrete. The basic definition of crack tip opening displacement (CTOD) is corrected based on the monitored variable of crack mouth opening displacement (CMOD). The improvedCTODcriterion, called the doubleCTODdcriterion, for the abnormality diagnosis of cracks in the concrete is constructed based on the fictitious crack model and linear asymptotic superposition assumptions of the concrete. The doubleCTODdcriterion is verified using two specimens of three-point bending notched beam. The verification results are reasonable and correct. The establishment of the doubleCTODdcriterion lays a solid theoretical foundation for the abnormality diagnosis of cracks in concrete structures (such as concrete dams) based onCMOD.
