摘要:
将裂缝扩展准则应用于混凝土重力坝裂缝扩展全过程分析,结合虚拟裂缝模型计算了经典混凝土重力坝模型的断裂特性,并与其他数值方法进行了对比。结果表明:利用该数值方法得到的混凝土重力坝模型的外荷载-裂缝口张开位移曲线及裂缝扩展路径与试验结果均吻合良好; 当给定了混凝土材料的起裂断裂韧度、断裂能、抗拉强度等参数后,即可采用该数值方法对混凝土重力坝裂缝扩展全过程进行分析。
Abstract:
Crack propagation criterion was used to analyze the complete crack propagation process in concrete gravity dams. Utilizing the criterion combined with fictitious crack model, the fracture behaviors for a classical concrete gravity dam model were calculated and compared with other numerical methods. The results show that the load versus crack mouth opening displacement curve and crack propagation trajectory in concrete gravity dam model are good agreements with experimental results. When some concrete material parameters, such as initial cracking toughness, fracture energy, tensile strength are given, the complete crack propagation process in concrete gravity dams can be analyzed by using the numerical method.
