| 摘 要： | 顺层边坡的失稳问题一直是工程地质学和岩石力学领域内极为瞩目和急待解决的问题之一。本文根据顺层边坡的地质背景及力学作用机制,抽象出了顺层边坡溃屈破坏的力学模型。利用板柱弹性稳定性理论,结合结构力学的知识,推导出了相应的计算公式。实例分析表明,利用文中的理论方法,并结合工程现场有效的量测手段,可方便、有效的判定顺层边坡的稳定性。

| Abstract: | The stability-losing of the consequent slope is one of the most urgent problems in practical engineering. Based on the geological background and mechanism, mechanical model of buckling failure for the consequent slope is given in this paper. According to the stability theory for elastic plane and the structure mechanics, formula has been deduced. A case study is presented finally, the result of which is in agreement with the practical states. The case study indicated that using the theory method in the paper, combined with the effective survey means in the site, the stability of the consequent slope can be gained. |
