| 摘 要： | 首先利用Monte-carlo法模拟了预制桩极限承载力概率分布,并结合静载荷试验数据,用Bayes原理修正其概率分布,得到了更符合实际的预制桩承载力概率分布,接着利用可靠度理论中的JC法进行了可靠度指标的计算.

| Abstract: | The limit bearing capacity probability distribution of prestress pile was simulated using Monte-carlo firstly,its probability distribution was amended using Bayes principle combining with static loading test datas,and bearing capacity probability distribution of prestress pile being more agreement with practice was got,then the reliability index was calculated using JC method in reliability theory. |
