【摘要】 采用时程分析法、运用ANSYS软件分析了岩质边坡在不同地震波入射方向下的动力响应规律。结果表明,位移放大系数随地震波入射角的增大,在0°~5°时增幅较大,出现拐点后减小;位移放大系数的最大值并非发生在垂直入射时,而是与垂直入射成一定角度;加速度响应也表现出同样规律,但没位移响应明显,且坡顶与坡底的变化规律差异较大。该方法为未来深入研究提供了理论参考。更多还原

【Abstract】 This paper analyzes the dynamic response of the rocky side slope under the different incidence angle of seismic waves using ANSYS and time-history analysis method.The results show that the amplification coefficient of displacement firstly increase and then decrease with the increase of incidence angle of seismic wave range between 0 and 5 degree.The maximum amplification coefficient of displacement is not appeared at the vertical incidence location.The response of acceleration also shows the similar laws.But it is less distinct than that of the displacement.Furthermore,it has some difference from the top of slope to the bottom of slope.Thus,it provides reference for the future research deeply.更多还原
