摘要
简述了岩质陡高边坡地震动力响应分析的基本原理与计算方法,建立了评价稳定性的计算公式。结合马崖高陡边坡实例,用反应谱法和时程分析法进行了计算,获得了动态特性、地震动力响应,并给出了可能滑裂面的抗剪断强度储备比值。其结果能够合理地评价其稳定性。
This paper gives the basic theory and computation method of high?steep rocky slope under earthquake loads and the formulae for evaluating slope stability. By numerical analyses of transient procass and spectrum, the dynamic characteristics, seismic responses,and reservation ratios of shearing strength of Mayan high?steep rocky slope are presented. The results can be used for seismic safety assessment of high?steep rocky slope.
