| Abstract: | The statistic principle of P s, f i and P sb statistic features for bored Pile was researched with the random field and the reliability theory.Problems of hamony in programme such as application of the correlation distance, pile diameter and the calculating range of P sb and f P was studied.The statistic feature of the limit bearing capacity reliability of bored pile was obtained according to the numerical result of 46 CPT curves at 17 of sites in Shanghai Region.Based on these results, the partial factors defining the bearing capacity of bored pile by CPT was given by complete reliability analysis. |
