摘要

摘要: 近水平厚层高陡斜坡岩层倾角小于10°，具有软硬相间或上硬下软的结构，常形成高陡斜坡或陡崖地形，主要以大型崩塌的形式发生破坏。在梳理国内外文献的基础上，从岩体破坏机制出发，对近水平厚层高陡斜坡崩塌的形成过程、破坏机制、失稳模式进行分析，总结归纳了6种地质力学模型，包括滑移-拉裂、塑流-拉裂、倾倒-拉裂、剪切-错断、剪切-滑移、劈裂-溃屈，并提出了相应的野外识别特征。

Abstract: Sub-horizontal thick bedding slope shows a gentle dip of approximately 0~10°and strata structure of hard on soft, or hard interbedded with soft. It forms a high and steep terrain and is prone to rock collapse. Reviewing a lot of references, failure process and initiation mechanism, as well as failure modes of high-steep slope in sub-horizontal thick bedding mountains are analyzed in terms of rock mass failure mechanism. Six geomechanic models are summarized such as slipe-tensile, creep-tensile, slipe-shear, shear-rupture, shear-slipe and split-bulk. Corresponding to the reconginition features of geological structure are also presented.
- sub-horizontal bedding slope /
- vertical tectonic joints /
- failure mechanism of rock mass /
- failure mode /
- geomechanic model
