土层性质对钻孔灌注桩孔径变化的影响

Research on Impact of Soil Conditions on the Variation of Pile Diameter of Bored Pile

考虑了基于土体随机场理论的土的相关距离,去除取样子样相互不独立的影响,对钻孔灌注桩实测成孔曲线进行了统计分析。采用Grubbs方法去除异常点的影响,并根据随机场理论求出均值和均值方差。最后根据K-S拟合分布检验法进行了分布检验,并对以上过程所得结果进行了分析讨论。

Based on the random field theory of soil,the coherence distance is taken into consideration to eliminate the influence from the mutual dependence among the samples. The measured values of bored pile diameter are analyzed. Grubbs method is employed to delete the exceptional data points and the mean and the deviation of the data is got through the random field theory. Finally,K- S method is used to survey the distribution of the data and some further analysis is made based on the process.
