摘要
为研究治理后的某炉渣高边坡动力响应问题,基于完全非线性动力分析理论,利用Flac^(3D)软件模拟边坡地震响应,获得了边坡在地震作用下的加速度放大系数、动位移及塑性屈服区分布的动力响应特性。结果表明:在动力荷载作用下,治理后的炉渣高边坡挡土墙顶部竖直方向和水平方向加速度放大系数分别约为1.44和3.34,具有较大的安全储备;边坡水平方向最大位移不大,且塑性区范围比治理前小,即炉渣高边坡稳定性得到了很大改善,治理措施有效。
To study dynamic response of a furnace slag high slope after treatment,the seismic response of the slope was calculated with the finite difference software Flac^(3D)based on the fully nonlinear dynamic analysis theory,and the acceleration amplification coefficient,dynamic displacement and the plastic yielding zone were obtained.The results showed that the action of dynamic load led to the top of retaining wall of a furnace slag high slope with accelera-tion amplification coefficients at about 1.44 and 3.34 respectively for the vertical direction and horizontal direction and with more safe reserves;the maximum magnitude of the horizontal displacement for the slope is not great and the plastic zones area is smaller after treatment,i.e.the stability of the furnace slag high slope is greatly improved and the treatment measures are effective.
