加拿大阿尔伯塔省海伍德山口沉积岩中的地层屈曲发生在陡峭的下倾和倾斜斜坡上。屈曲模式由层理厚度决定。我们区分了在没有交叉裂缝的岩层中发育的欧拉屈曲，在具有交叉裂缝的岩层中形成光滑弯曲的层理表面的块曲屈曲，以及在厚度大于0.1 m的岩层中随着岩石块体的大旋转而发育的块曲。在厚度小于0.1米的岩层中发育类似于褶皱的褶皱状褶皱。扣可以进一步移位，形成屋顶和墙壁结构或瀑布。关键词：屈曲，临界荷载，边坡稳定性，天然岩质边坡。
Buckling of beds in the sedimentary rocks in the Highwood Pass, Alberta, Canada, occurs on steep underdip and dip slopes. The modes of buckling are determined by bedding thickness. We distinguish Euler buckles that develop in beds without cross fractures, block-flexure buckles that form with smooth buckled bedding surfaces in beds with cross fractures, and block buckles that develop with large rotations of rock blocks in rock layers more than 0.1 m thick. Chevron buckles resembling chevron folds develop in beds less than 0.1 m thick. Buckles can be displaced further to form roof and wall structures or cascades. Key words : buckling, critical load, slope stability, natural rock slope.
