高水平应力场条件下巷道顶底板稳定性模拟研究

Simulative study of stability of tunnel's top plate and soleplate under high-level stress

阐述了利用ANSYS有限元数值模拟软件,建立采场和巷道的三维有限元模型,开发了三维实体巷道锚杆支护辅助设计系统(ANSYSBOLT),对高水平应力场条件下实体巷道锚杆支护的作用机理进行了数值模拟分析,并计算分析了实体巷道锚杆支护结构和参数对巷道顶底板稳定性的影响。

By means of ANSYS finite element data simulation software kit, the 3D finite element model of stope and tunnel is established; and the 3D tunnel＇s bolt support design system （ANSYSBOLT） is developed. The data simulation study of function ＆ mechanism of bolt support under high--level stress is done. And the influence of structure ＆ parameters of bolt support on stability of tunnel＇s top plate ＆ soleplate is calculated.
