本文结合沙牌碾压混凝土拱坝坝体设置三条诱导缝，坝体设置周边应力释放缝，坝体不设缝的三种情况，进行了整体结构模型试验。分析了坝体的应力、变形及破坏特性，为工程的设计和施工提供了参考依据．
Combined with Shapai RCC arch dam three inducing joints, the dam to set the surrounding stress release joints, the dam body is not sewn three cases, the overall structural model test. The stress, deformation and failure characteristics of the dam are analyzed, which provides a reference for the design and construction of the dam.
