【摘要】 本文运用FLAC3D对澜沧江左岸某边坡进行地震作用下的数值模拟,通过人工合成50年超越概率10%加速度时程的地震波,将其利用积分转换成应力时程输入到边坡模型中,并采用莫尔-库仑本构模型分析了该某边坡在地震波作用下剪应力位移矢量的变化情况,结果表明:应力方面,坡肩出现剪应力集中的现象,随着最大主应力和最小主应力两者差异增大,边坡将发生剪切破坏;位移方面,在0.2g加速度下,边坡水平位移达98cm。更多还原

【Abstract】 This paper uses FLAC3D to make the numerical simulation for a slope on the left bank of Lancang River under the seismic waves.The results indicate: on the side of stress,the shear stress concentration occurs at the slope shoulder and the slope will have the shear failure as the difference increases of the maximum principal stress and the minimum principal stress;and on the side of displacement,the horizontal displacement reaches 98 cm at 0.2 g acceleration.更多还原
