摘要
以兰州市北环路南坡坪—慈恩寺段边坡为原型,利用MIDAS-GTS有限元计算软件,分别建立了不支护开挖、锚杆支护开挖和框架梁锚杆支护开挖的数值计算模型,分析了不同支护状态下边坡水平位移、竖向位移、最大剪切应变及边坡稳定系数等参数的变化,为边坡制定合理的支护方法提供参考.
Based on the Beihuan road section in Lanzhou City from Nanpoping to Ciensi, using MIDAS-GTS finite element software,excavation calculation model with non- support,anchor support and frame support is set u p, and furthermore,horizontal displacement,vertical displacement,maximum shear strain and slope stability coefficient are analyzed, which provides references for the feasible slope support.
