摘要
本文针对地震这一动力因素，利用有限单元数值模拟方法，研究了公伯峡坝前倾倒体对地震的敏感性问题。结果表明，倾倒体的地震敏感性较高，在地震基本烈度Ⅵ以上时其稳定性迅速恶化。
Regarded the earthquake as the dynamic factor, this paper analyses the sensivity of the tilt slope in front of the Gongbo Gorge Dam to earchquake by means of Finite Elements Method.The results indicate that the tilt slope has higher senstivity, and its stability may rapidly decrease to a critiCal degree as the basic earthquake intensity reaches as degree higher than Ⅵ.
