本文采用ＪＣ法，对三峡风化砂回填地基承载力进行了可靠度分析。计算结果表明，采用随机场理论统计抗剪指标时，所得地基承载力可靠度指标高于二级建筑物的目标可靠指标。
In this paper, JC method is used to analyze the reliability of bearing capacity of backfill foundation in the Three Gorges Project. The calculation results show that the reliability index of the bearing capacity of the foundation is higher than the target reliability index of the second-grade building when using the random field theory to calculate the shear resistance index.
