| 英文摘要 | Slopes composed of sedimentary rocks have different forms and internal structures, which are determined by the properties and occurrence of strata. Vertically-bedded slopes, dip-bedded slopes and horizontally-bedded slopes are common in nature. During and after the process of slope formation, the component forms and relative positions of strata are constantly changing and developing. In one case, deformation develops with time without variation in stress; in another case, there is no alternation in strain, but the stress decreases with time, i.e. relaxation. The former is the so-called rock creep deformation. There are many examples of slope failure due to rock creep deformation. This paper describes yielding break landslides in horizontally-bedded rock slopes caused by the development of rock creep under the long-term effect of the least principal stress (σ3) gradient. Here the σ3-effect is the process of landsliding due to such a mechanical mechanism. |
