地震荷载作用下高边坡稳定性分析OACSTPCD
Analysis on the Stability of High Slope Under Seismic Loads
应用地震对高边坡的破坏机理,以重庆渝中区洋河小学头塘校区旁边的高边坡为研究对象,对地震荷载下高边坡的稳定性进行分析。利用有限元软件MIDAS/GTS ,建立三维数值模拟模型,初步分析地震荷载作用下带有软弱夹层的高边坡位移及应力变化规律。由分析结果可知:沿地震波方向的高边坡位移明显增大,其他方向位移变化较小;软弱夹层上部较下部位移变化大。高边坡安全系数的计算可为其加固提供可靠的理论依据。
Taking the high‐slope near Toutang Campus of Chongqing Yanghe Primary School in Yuzhong District as the research object ,this paper analyzed the stability of high slope under seismic loads with the failure mechanism .By using the finite element software MIDAS/GTS ,a 3D numerical simulation model was established to analyze the displacement and stress variation of high slope with weak interlayer under seismic loads .The results showed that the displacement of …查看全部>>
