摘要
以沙牌碾压混凝土拱坝的模型试验为例,运用断裂力学理论,推导出了模型破坏试验中诱导缝模拟的相似条件,得出了在碾压混凝土拱坝破坏试验中,原型与模型拱坝要满足常规结构模型试验的相似关系,同时诱导缝模拟还要满足诱导缝开裂相似条件及诱导缝抗剪断强度相似条件的结论。
Using the theory of fracture mechanics and giving an example of model test of Shapai roller compacted concrete arch dam,several similarity conditions of induced slot in model failure test are developed.A conclusion can be drawn that in failure test of roller compacted concrete arch dam,the arch dam must satisfy the simulated relation of conventional model failure test.And the induced slots of prototype and model must satisfy the simularity condition of cracking and shear strength.
