| Abstract: | According to the loading property of composite pile foundation, the probabilistic model for reliability analysis is proposed. Combined with practical project, the reliability index β on the bearing capacity of composite pile foundation, corresponding to total safety, is calculated, and the sensitivity of index β is investigated. |
