摘要
结合沙牌碾压混凝土拱坝工程实际,采用结构模型试验和三维非线性开裂计算相结合的研究方法,着重研究含诱导缝的碾压混凝土拱坝的结构应力与开裂特性,获得了大坝的应力分布、大坝及诱导缝开裂破坏形态、破坏过程及破坏机理,模型试验与数值计算所得结果相近,为沙牌工程的设计和施工提供了参考依据。
In connection with Shapai RCC arch dam this paper adopts the approach that structural model test model combines with 3 D non linear fracture calculation to study structure stress & fracture property in Shapai RCC arch dam which includes inducing joints the results of model test are in accord with those of calculation. the distribution of dam stress fracture pattern process & mechanics of dam & inducing joints due to over loading are achieved for reference of design and construction in Shapai project.
