坝体混凝土损伤-断裂模型

Damage fracture model for concrete of dam

提出的损伤断裂耦合模型，是将混凝土坝体视为一个损伤场，并以此为背景进行坝体损伤断裂耦合分析．所编制的有限元程序可以计算混凝土坝在荷载、温变等因素作用下的损伤情况、开裂部位、裂缝深度及扩展形态、有损伤和有缝情况下的工作性态等．

A damage fracture coupling model is established. For this model, the dam is regarded as a damage field. The damage fracture coupling analysis of dam is dependent on this field. Using the FEM program, the damage state, crack place, crack depth and crack form of the dam under loading and temperature are calculated.
