摘要
针对高混凝土坝可靠度分析中极限状态函数不能显式表达且随机变量复杂的特点,基于变量的随机敏感性因子改进响应面法,提出了适用于高混凝土坝复杂结构系统的改进响应面法。算例结果表明,该法计算效率高、实用性强,是高混凝土坝及复杂水工结构物可靠度分析的较好途径。
Considering the implicit performance in limit state equation and complex random variables for reliability analysis of high concrete dam,an improved response method based on stochastic sensitivity analysis is established.The new method is proved to be effective and practical,which is a good tools for reliability analysis of complex hydraulic structure and high concrete dam.
