【摘要】 在建立考虑自重、地震作用和地下水共同作用的二维顺层岩质边坡的简化力学模型的基础上,根据弹性薄板的稳定理论,利用能量法探讨顺层岩质边破溃屈失稳机理,并推导了相应的计算公式,通过实例计算,比较了本文所述方法的分析结果与只考虑了岩板自重作用的弹性板分析结果,且经现场勘察,证明了本方法用于溃屈失稳分析的可行性。同时表明地震作用和地下水作用在顺层岩质边坡稳定性计算中是不可忽视的因素。更多还原

【Abstract】 A predigested mechanical model of the two-dimension consequent rocky slope was built considered the influence of deadweight,earthquake and groundwater.Based on it and according to stability theory for elastic plane,a study on the mechanism of consequent rocky slopes’ buckling failure by energy method was carried out,and a computing formula has been deduced.The comparison between the results in this paper with the results obtained from the traditional elastic plane method only considered the influence of deadweight,reveals that the method presented in this paper is applicable for such analysis.更多还原
