摘要
建立了基于分载法的拱坝可靠度分析模型 ,采用了处理后的差分值代替荷载效应为隐式时的偏导数 .定性地分析了该方法成果的可靠性 ;通过实例的比较计算 ,定量地证明了成果的稳定性 ;同时 ,还研究了各随机变量对拱坝可靠指标的影响 ,对设计中随机变量的选取有参考意义 .
Unified design standard for reliability of hydraulic structures” demands that the theory of structural reliability be applied to the desigin of hydraulic structures. The load distribution method is the main method for stress analysis of arch dams. In this paper, formulations for reliability analysis of arch dam are developed based on the load distribution method. The accuracy of the method is proved to be satisfactory. The effect of random variables on the reliability index is discussed.
