摘要
考虑岩土不确定性因素的影响,将土体内摩擦角和土体重度设为正态分布的随机变量。运用VB语言,基于验算点法编制了加筋土挡土墙全墙倾覆稳定性的可靠度分析程序。通过调整设计参数,可以在满足达到目标可靠度指标的前提下选择较为经济的方案,进行结构优化设计。
Considering the influence of uncertain factors of geotechnical engineering,the authors set internal friction angle and gravity as normal random variables.Based on JC method,the authors programmed reliability degree analysis program of overturning stability of reinforced soil of retaining wall.Through adjusting design parameters,we can choose more economical scheme premising it meets objective reliability degree index.Through calculating practical engineering,the authors find the result meets the practical situation,thus it's verified that the program is correct and applicable.
