摘　　要：作用模型不定性整体系数FSUNC是坦萨(Tensar)设计手册中加筋土挡墙设计的一个参数,现阶段我国相关规范中未设置此参数。依托山西晋中地区某二级公路改扩建项目,利用GEO5软件计算不同填土高度下该参数的取值对加筋土挡墙整体稳定性的影响,并结合计算结果提出相关建议,为加筋土挡墙设计提供参考。The uncertainty global coefficient FSUNC of the action model is a parameter in the design of reinforced soil retaining wall in the Tansar Design Manual.At this stage,this parameter is not set in the design of relevant specifications in China.Relying on a secondary highway reconstruction and expansion project in Shanxi Jinzhong area,GEO5 software is used to calculate the influence of this parameter value on the overall stability of reinforced soil retaining wall under different filling heights,and combined with the results of the calculation to put forward the relevant recommendations and to provide reference for the design of reinforced soil retaining wall.
