| 摘要: |
| 分析了澧河段梁式渡槽桩基础的破坏模式，建立了相应的功能函数，计算得出混凝土单桩的可靠指标。最后，把桩和地基土作为整体，运用随机有限元法计算了校核工况下桩基础的可靠指标。 |

| Abstract: |
| The failure models of the pile foundation of the girder flume in the Li River are analyzed, the corresponding functional functions are established, and the reliability index of a single concrete pile is calculated. Finally, considering the piles and foundation soil as a whole, the reliability index of the pile foundation with check working conditions is calculated by using the stochastic finite element method. |
| Key words: reliability index,failure model,stochastic finite element,pile,pile foundation,flume |
