摘　　要：以三峡库区重庆段某架空直立式码头工程为依托,对该结构进行有限元分析的静力计算,结合Monte Carlo法,对该码头下部结构的桩基、钢横撑、钢前撑等主要受力构件进行可靠度分析。各构件的可靠指标大小均满足规范要求,其中前排桩基及钢前撑的最小可靠指标分别为5.078和4.186,而所有钢横撑的可靠指标均大于8。随后采用灵敏度分析法及随机变量散点分析法对影响该码头下部结构可靠度的主要因素进行了探讨。Based on the overhead vertical wharf engineering in the Three Gorges Reservoir area of Chongqing, we carried the structural static＇s finite element analysis, and carried the reliability analysis on pile foundation, steel crossbars, and front steel support such as the main force components of the wharf＇s substructure combined with Monte Carlo method. All the component＇s reliable indicator meet the regulatory requirements, the minimum reliable indicator of the front pile foundation and front steel support are 5.078 and 4.186, and the reliability index of the steel crossbars are all greater than 8. Then, we used the sensitivity analysis and the random variables scatter analysis to discuss the main factors of the substructure＇s reliability.
