基于FLAC3D的边坡地震反应分析
Seismic Response Analysis of Slope Based on FLAC3D
【摘要】 基于完全非线性的动力分析方法,对边坡地震作用下的稳定性开展研究。分析得出:地震作用下,边坡最大永久位移主要集中于坡面;对于垂直方向上布置的关键点,随高程增加,位移时程表现为"放大",加速度时程呈现"放大"和"滞后";对于水平方向布置的关键点,由坡内向外,位移时程表现为"放大",加速度时程却出现"衰减"和"同步"。研究结果有助于进一步揭示边坡在地震作用下的失稳机制。
【Abstract】 Based on fully non-linear dynamic analysis methods,slope stability under earthquakes was analyzed.It was shown that: Under earthquakes effect,the maximum permanent displacement focused mainly on the surface of the slope;For the vertical key points,with the elevation increasing,the displacement-term expressed as "zoom",the acceleration-term showed "zoom" and "lag";For the horizontal key points,from inside to outside,the displacement-term performed as "zoom",the acceleration-term showed "decay" and "synchronization".The results were helpful to further researches on the mechanism of slope instability under earthquakes.
