Abstract

Abstract: Parameters of action and resistance factors for reinforced earth structures and distribution modalities have marked effect on reliability calculation. According to feature of reinforced earth structures and experimental results, the authors apply mathematical statistics method to analyze physical and mechanic parameters of filling materials gravity(γ) and reinforced materials tensile force, and results show reasonability by engineering examples checking. The results give a reference to the new c

Key words: reinforced earth structures, gravity, tensile force, mathematical statistics, reliability

摘要： 在进行加筋土结构可靠度分析计算中,加筋土结构作用和抗力的统计参数及其分布形式对其可靠指标有显著的影响.笔者针对加筋土结构本身的特点,结合试验结果,采用数理统计的方法,对加筋土填料(主要为砂卵石填料)的重度γ、加筋材料的拉力进行统计分析,并将其应用于工程可靠度验算,其结果表明是合理的,可为加筋土结构设计规范修订提供一定的参考
