摘要
采用Midas/GTS有限元软件对拟建的隧道洞口边坡进行了数值分析,计算结果表明,边坡的应力、位移均较小,均未超过控制标准,不易造成边坡体的破坏;在静力作用下不会发生整体滑动,边坡的安全储备系数可以满足要求拟建隧道洞口区的施工及运营安全。
The numerical analysis of planed tunnel portal side Slope was carried out with Midas/GTS finite element software. The calculation result indicated that side slope stress and displacement were litter and not exceed control standard, which uneasy to make side slope damage and will not integral slipping under static stress function, the emergency capacity coefficient can satisfy construction and running safety of planed tunnel portal section.
