斜坡楔体破坏是指两个产状不同并相互切割的结构面上的岩石楔形体,沿着两个结构面的交线产生的向着斜坡临空方向的滑动。这种破坏是岩坡最常见的破坏型式之一,因而引起了国内外许多研究者的注意,不少研究者利用极射赤平投影、实体比例投影及工程地质图解法、解析法等对楔体破坏进行了分析研究,取得了很大的成绩。但由于楔体破坏是一个空间课题,因而利用解析 Slope wedge failure refers to the two rock wedges on the structural face that are different in shape and cut to each other, sliding along the intersection of the two structural faces to the direction of slope. This damage is one of the most common damage patterns of rock slopes, and it has attracted the attention of many researchers at home and abroad. Many researchers use polar stereotactic projections, physical proportional projections, engineering geological diagrams, and analytical methods for the wedge body. Destruction conducted analysis and research and achieved great results. However, because the wedge damage is a space issue,
