【摘要】 本文针对大型复杂地下洞室结构可靠度分析中其功能函数不能显式表达的特点,提出了基于三维非线性有限元与响应面法、JC法相结合的可靠度计算方法,将之用于已运行30余年的四川省映秀湾水电站地下厂房洞室结构的可靠度分析表明,成果与实际监测数据一致,精度满足工程要求,计算效率高,实用性强,是大型地下洞室结构及复杂水工结构可靠度分析的良好途径。更多还原

【Abstract】 Considering the difficulty of setting up the performance function in Structure reliability analysis oflarge complicated underground cavern, an calculation method on the structure reliability that combine 3Dnon-linear finite element method, surface response method and JC method is founded in this paper. The method isused on the cavern structure reliability analysis of the underground powerhouse of Yingxiuwan water powerstation in Sichuan province that has been operated for more than 30 years. As the result is compared with themonitoring data, it shows that the method can get good precision, high performance, and well practicability. Thenew method is proved to be a good means in the structure reliability analysis of large underground cavern andother complicated hydrostructures.更多还原
