碾压混凝土重力坝的安全评价方法和安全标准的研究

在研究碾压混凝土重力坝失稳破坏机理的基础上，提出以准弹性准则作为碾压混凝土重力坝的设计准则。以三峡工程为例分析了碾压混凝土面力学参数、刚度对大坝应力和稳定的影响。此外，详细介绍了与安全准则配套的安全系数取值问题，所得结果对工程设计及有限元数值方法实用化有普遍的参考意义。

Study on Safety Assessment Method and Safety Criteria of RCC Gravity Dams

Based on the study of the failure mechanism of RCC gravity dams,the hypoelastic criteria are proposed as the design criteria of RCC gravity dams.The Three Gorge Project taken as an example,the effects of mechanical parameters of bedding surfaces and rigidity on the stress and stability of RCC dams are analysed.And the determination of design safety cofficient corresponding to the safety criteria is comprehensively studied.The result may be referred to in engineering design and construction and the application of FEM.
