摘要
利用可靠度理论对从国内收集到的25组CFG桩复合地基承载力试验数据进行了概率统计处理。借助无量纲计算模式,计算不同载荷组合下CFG桩复合地基承载力的可靠度指标,并分析了各随机变量对可靠度指标的影响程度。为评价常用经验公式ksp,f的可靠性提供一定的参考。
The 25 test data of the composite foundations of CFG piles collected from all over the country are processed statistically according to reliability theory. The reliability indexes of the composite foundations of CFG piles is calculated by thenon-dimensional calculation mode and the influence extent of each stochastic variable on the reliability index is also analyzed. For evaluating the reliability of the conventional empirical formulakspf,, some references may be provided.
