高RCC拱坝结构可靠度分析与破坏试验研究

Structural reliability analysis and its failure tests on the high RCC arch dam

结合“九五”国家科技攻关课题 ,采用坝体结构可靠度数值计算与坝体破坏模型试验相结合的方法 ,分析了沙牌高碾压混凝土拱坝设缝后诱导缝及坝体开裂失效的可能性 ,以及大坝结构的安全性和可能的破坏机制等工程关键技术问题 。

Combined with the national scientific and technical subjects during the Ninth-Five-Year Plan period, the structural reliability calculation and fault model test of dam body are combined and applied to analyze the probability of cracking and failure of induced joint and dam body of the Shapai High RCC Arch Dam, and to solve the security and probable failure mechanism of dam structure, in order to provide reference for the design and construction of project.
