| 摘 要： | 将正交试验方法应用于加筋土挡土墙的缩尺模型试验,采用4组试验模拟墙后填土与墙面板之间存在差异沉降的挡墙工作状态,量测了各级差异沉降下的筋带变形.通过对筋带延伸率、筋带密度、筋带与面板连接方式3个因素的二水平试验结果的分析,提出差异沉降下筋带变形可以用指数曲线描述,并对试验现象加以分析.图5,表4,参9.

| Abstract: | In this paper,Orthogonal Test Method is used in the reduced model tests of reinforced retaining wall.Four model tests were performed to study their working behavior,in which the differential settlement between the facing and backfill induced by some reasons.The deformation of reinforcements were measured in every grade of differential settlement.Three alterable factors that varying on two levels are:the extensibility and the density of the reinforcements,the join manner of the reinforcement and facing.The test data indicate the deformation of reinforcements can be described very well by exponential curve;the experiment phenomena were analyzed too.5figs.,4tAbs.,9refs. |
