Based on the test data of prestressed high strength concrete(PHC) pile at north bank of the Yangtze River in Nanjing and the limit state equation of dimensionless random variables
the standard of the integral reliability level in the current Specifications of Foundations is calculated with the method of calibration
and the reliability index is calculated. Further more
the influence of general assurance coefficient
loading effect ratio and different load compositions on the reliability index is investigated. Finally
the partial coefficient of the resistance is calculated. It is shown that the reliability index is related to general assurance coefficient
loading effect ratio and different load compositions. In addition
it is also indicated that the influence of general assurance coefficient on the reliability index is remarkable
whereas the influence of different load compositions on the partial coefficient is weak.
