摘要
以三峡库区某架空直立式码头为例,采用基于有限元软件ANSYS的Monte Carlo法,对架空直立式码头桩基进行了灵敏度分析、散点图分析,并讨论了桩基在各种工况组合作用下的可靠指标.结果表明船舶撞击力对码头桩基的可靠度计算起着决定性作用,码头桩基可靠度指标基本满足规范要求,可靠指标计算方法和结果可为类似码头桩径优化设计提供参考.
With the overhead vertical wharf in the three gorges reservoir area as an example, the paper used Monte Carlo method based on the ANSYS finite element analysis software to not only analyze sensitivity and scatter plot but also explore reliability index of piles under different condition. The analysis results demonstrated that impact force plays a decisive role in reliability calculation of pile foundation and reliability index of piles attain the standard al- most. The calculation methods and results of reliability index can provide a reference for optimizing the pile diameter design of similar wharf.
