中文摘要：
以河北省邢汾高速公路土工格栅加筋高填方路堤工程为背景,用正交设计表L18（37）安排了54组拉拔试验,分析了7个因素对加筋土界面摩擦特性的影响。试验结果表明,影响加筋土界面摩擦特性的因素主次顺序为上覆荷载、含水率、筋材距试验箱侧壁距离、拉拔速率、格栅类型、筋材水平埋入长度、干密度。其中,上覆荷载、含水率、筋材距试验箱侧壁距离、拉拔速率对筋-土界面摩擦特性的影响特别显著。通过分析筋-土界面拉拔摩擦系数与7个因素的关系,得到了各因素的优水平以及各因素在拉拔试验过程中的变化规律。
英文摘要：
Based on the geogrid-reinforced high embankment project of Xingfen Expressway in Hebei Province,54 pull-out tests were designed with orthogonal table L18（37）,and seven factors were analyzed for their influence on interface friction characteristics.The results show these factors can be sorted according to the levels of their influence on interface friction characteristics of reinforced soil in the order of cover load,water content,distance from geogrid to chamber side wall,pulling rate,geogrid type,embedded length of reinforcement,dry density.Among them,cover load,water content,distance from geogrid to chamber side wall and pulling rate have significant influence on the interface friction characteristics of reinforced soil.The best level and the rules governing the variation of each factor during the pull-out test were obtained by analyzing the relationship between the interface friction coefficient and the seven influence factors.This test provides reliable reference for structural stability analysis of reinforced soil.
