The frame anchor plate is a new retaining structure for reinforcing a fill slope. Due to the lack of theoretical research, engineers cannot accurately evaluate the retaining structure’s effect on the stability of slopes under design and construction. This paper used the orthogonal experimental design method to analyze the sensitivity of each parameter to evaluate the influence of each parameter on the slope safety factor. The results of the orthogonal experimental design application show that the parameter sensitivity rankings obtained by range and variance analyses are consistent. Among the parameters studied, the section length of the frame beam and the length of the anchor plate obviously influence the safety factor. This research can provide some basis for the optimization design of a fill slope reinforced by a frame anchor plate.

框架锚板是一种用于加固填方边坡的新型支护结构。由于缺乏理论研究，工程师无法准确评估设计和施工中支护结构对边坡稳定性的影响。本文采用正交试验设计方法，分析各参数的敏感性，评价各参数对边坡安全系数的影响。正交实验设计应用的结果表明，极差分析和方差分析得到的参数敏感性排序是一致的。研究的参数中，框架梁的截面长度和锚板的长度对安全系数影响明显。该研究可为框架锚板加固填方边坡的优化设计提供一定的依据。
