针对边坡在地震荷载作用下的动力稳定性问题,将边坡矢量和分析方法与动力有限元法相结合,对边坡进行动力稳定性分析,并依据边坡的安全系数时程曲线,评估边坡在地震荷载作用下的稳定状态。采用均质边坡进行了算例验证,检验了方法的合理性,最终用其对一个高陡边坡进行了动力稳定分析,计算结果表明:动力矢量和法可合理地评估边坡的动力稳定性状态。
Aiming at the dynamic stability problem of slope under earthquake load, the dynamic stability of slope is analyzed by combining the vectorial and analytical method of slope with the dynamic finite element method. According to the time course curve of safety coefficient of slope, Stability of slope under earthquake load. An example is given to verify the stability of the slope with a homogeneous slope. The stability of the slope is verified by a dynamic stability analysis. The calculation results show that the dynamic vector sum method can reasonably estimate the dynamic stability of the slope Sexual status.
