摘要
针对加锚岩体的数值模拟,通过锚杆轴向位移自由度的引入,建立了考虑界面黏结滑移性质的加锚岩体组合单元模型,并导出了组合单元的相关列式.算例表明,采用该模型进行加锚岩体分析时,锚杆可以穿过实体单元的任意部位,可为真实地反映锚杆的复杂几何布局与工作特点提供便利.
With the axial displacement of anchor rods taken as a degree of freedom, a combined element model for anchored rock mass with consideration of interface properties was developed for numerical simulation of the rock mass, and the corresponding formulas were deduced for combined elements. Case study shows that, with the model used for anchored rock mass analysis, the anchor rod may go through anywhere of the block element. As a result, the present model makes it easy to truely reflect the complicated geometric layout and operational characteristics of anchor rods.
