摘要
运用一次二阶矩和Monte Carlo法对嵌岩桩竖向承载力进行了可靠性分析研究。通过一个具体算例分析了分布函数的类型、变量相关性对可靠度指标的影响 ,并分别讨论了可靠度指标与变异系数、嵌岩深度、桩径、活恒载效应比以及安全系数的关系 。
The reliability of the vertical bearing capacity of rock-socketed piles is analyzed using FORM and Monte-Carlo.Through an example,the influence of distribution function types and variable correlation on reliability index is analyzed.The relations between the reliability index and such factors as the variation coefficient,the rock-socketed depth,the diameter of piles,the live and dead load effect ratio as well as the safety factor are discussed.Some beneficial conclusions are reached.
