| 摘 要： | 为了利用可靠度方法对管道进行风险评价,解决可靠度分析变量过多,模型复杂,计算困难的问题,结合管道跨越工程,利用最优化原理,将最优化蒙特卡罗方法与随机有限元方法结合,在确定基本有限元模型和最优化可靠度数学模型后,根据随机过程对基本变量进行正态化处理,确定出基本统计量的数字特征和单元之间的相关系数,合理控制计算精度,进一步确定出失效概率、可靠度值,通过显著性分析找出主因素,为结构参数优化提供合理依据。通过假设检验,验证了分析结果的合理性,为管线的风险评估提供新思路和方法。 |

| Abstract: | To obtain the safety assessment of pipelines based on reliability therory,too many variables in the complex model are calculated.Combined with the engineering of crossing over pipeline,using optimization theory,the optimized Monte Carlo method is integrated with stochastic finite element methods.Ater the basic finite element model has been determined and the reliability of the mathematical model has been optimized,basing on stochastic process,the basic variables are normal treated.The figure features of bas... |
