| Abstract: | On the basis of the random theory the statistic principle has been studied, from which the statictic characteristics of the bored pile, P s,f i and P sb , can be derived. The coordination of the correlation distance, the cross section dimensions and the calculation range of the end resistance in the programing has been also researched. And then the statistic characteristics of reliability indices in determining the bearing capacity of bored pile by means of CPT have been obtained according to the calculation results of 46 curves on the 17 sites in Shanghai region. |
