摘要

采用无量纲随机变量的极限状态方程，结合天津市钻孔灌注桩试桩资料进行可靠度分析。采用了JC法和Monte Carlo法两种方法进行可靠指标的计算，并对影响可靠指标的各种因素进行了分析。还计算了单桩承载力的抗力分项系数。

Abstract

Based on the static test data of bored piles in Tianjin

a reliability analysis of the bearing capacity of single bored pile is made by utilizing the limit state equation of dimensionless random variables. The index of reliability of the single bored pile is calculated with both JC method and Monte Carlo method. The influence factors on the reliability index are also analyzed. Finally

the resistance partial factor is determined by utilizing optimization method.
