| 摘 要： | 该文从薄板稳定的能量法出发,推导出不同情况下斜坡弯曲失稳的判据。应用此判据表明,它既方便又更符合实际情况。近来发现由于岩层滑移-弯曲而产生的滑坡,本文就某些实例的形成机制进行了讨论,并提出蠕变滑移-弯曲的破坏机制的概念。

| Abstract: | Toppling-falling and sliding-bending are the most common failure types on consequent scarpand consequent dip slopes. Both types are related to the buckling deformation of bedded rock masses.Based on the energy method of the stability analysis of thin plates, criteria of buckling failure of conse-quent dip slopes are deduced. The criteria are more theoritical than that deduced from the deformationof the beam. Its application shows, that it is not only convenient but also more consistent with the ac-tual situation. Recently a specific kind of landslides developed from progressive sliding and bending(buckling) deformation were revealed by field geological investigations. The forming mechanism ofsome case histories are discussed, and the concept of creep-buckling failure mechanism is suggested. |
