摘要
结合新乡地区深层搅拌桩复合地基静载荷试验数据,采用无量纲随机变量的极限状态方程进行了可靠度分析,采用JC法对其进行了可靠指标的计算,并分析了不同荷载效应比ρ对可靠度指标的影响,得出可靠度指标β随ρ的增大而增大的结论。
Based on the static test data of deep-mixing piles in Xinxiang, 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 deep-mixing piles is calculated with JC method, and the influence of the reliability index with the alteration of load effect specific p is analyzed, get the conclusion that the reliability index β increases with ρ.
