基于人工神经网络的沙牌RCC拱坝可靠度分析

Reliability of Shapai RCC Arch Dam Based on ANN Method

为解决拱坝可靠度分析中响应与荷载及参数间难以用显示函数表示的问题 ,将非线性分析中的人工神经网络方法应用于含诱导缝的高碾压混凝土拱坝的结构可靠度分析。计算得出沙牌拱坝上下游坝面及诱导缝结点的可靠度指标β,进一步完善和补充了“九五”国家科技攻关的内容 。

Application of ANN method for the reliability analysis of high RCC arch dam with induced joints, which is the country's tackling project in 'Ninth-Five-Year', solves the problem to dormant function relation between loads and response. The β of the dam and induced joints is calculated with the method. Probability analysis supplements and completes the tackling contents, provides reference for engineering design and construction as well.
