Abstract:
In order to adopt the probability limit states method to design manual hole digging pile, on the basis of the static test data of the pile in Shenyang, the reliability analysis of the vertical bearing capacity of single pile is made by using the limit state equation of dimensionless random variables and the reliability index is calculated by the JC method. What is more, the target index of reliability and the resistance partial coefficient in the local Specification of Foundations is got and the influence factors on the reliability index are also analyzed. At last, It is shown that the influence of loading effect ratio and different load compositions on the reliability index is to a certain extent, the influence of distribution types of resistance on the reliability index is remarkable, whereas the influence of different load compositions and loading effect ratio on the resistance partial coefficient is weak.
