| 摘 要： | 根据碾压混凝土拱坝诱导缝的构造特点，利用大比尺楔入劈拉试验成果，将诱导缝在稳定扩展中断裂过程区应力分布与相应的变形（张开度ω）联系起来，建立了诱导缝的等效裂纹断裂模型。利用等效裂纹断裂模型，计算了某碾压混凝土拱坝诱导缝的等效强度．结果表明，等效强度可以作为诱导缝的开裂准则。

| Abstract: | Based on the avaliable experimental for large scale speciments of concrete , a crack-equivalence fracture model is proposed for crack diector of RCC arch dam ,The stress distribution in the fracture process zone is incorposated into the model .An equivalence strength for crack director of a RCC arch dam was calculated by using the proposed model The results indicate that equivalence strength can be used as the fracture criterion for crack director . |
