以长沙商贸旅游职业技术学院工程边坡为研究案例,初步探讨了软质岩顺层边坡的非典型溃屈型滑坡机制。该滑坡是一种新型的溃屈破坏型式,将之命名为非典型溃屈型滑坡。非典型溃屈型滑坡的特征是:软质岩顺层边坡,滑动面不临空,坡趾前方一定距离处的坡底岩体弯曲-隆起、被损伤;尚未出现分阶段演化特征或暂时不能确定分阶段演化,可能的演化模式是弯曲-隆起带顶部剪断破坏;当坡底的岩体(板梁)达到屈服或屈曲时,即最先是弯曲-隆起带顶部剪断破坏时,滑坡可能再次失稳滑动。
Taking the slope of Changsha Commercial and Tourism Vocational and Technical College as a case study, the mechanism of atypical collapse-landslide along the soft rock bedding slope is preliminarily discussed. The landslide is a new type of ulcer damage, named it atypical collapse type landslide. The characteristics of the atypical collapse landslide are: soft bedding bedding slope, the sliding surface is not empty, and the slope bottom rock mass at a certain distance in front of the slope toe is bent-uplifted and damaged; the staged evolution characteristics have not appeared yet or are temporary It is not possible to determine the evolution in stages. The possible evolutionary model is shear failure at the top of the bend-uplift zone. When the rock mass (plate beam) at the bottom of the slope reaches yielding or buckling, ie the bend is the first to be bent-the top of the uplift zone is damaged, Sliding instability.
