| Abstract: | Based on the model of random fields of soils around the pile, the authors carry out some study on the statistical theory on the vertic al bearing capacity of single-pile and it enhances the design level of pile's capacity from the traditional method of permissible stress to that of probability limit state based on theory of reliability. The example is based on the data supplied by two bridge. |
