摘要: 基于不连续介质变形体的界面应力元法建立了加锚岩体新的数值模型，该模型可以仿真各种加固锚件的复杂几何布局，对加固锚件的位置、长度、倾向、倾角等均无任何限制和要求。数值算例表明：文中的计算模型能够较好地揭示加锚岩体的工作性态，具有广阔的应用前景。

Abstract: Based on the interface stress element model for discontinuous medium of deformable body, a new numerical model is proposed for anchored rock mass in this paper. The model can fully imitate all kinds of reinforcing bolts that have complex geometry distribution. No limitations are required on the position, length, direction, angle of reinforcing bolts. The results of the numerical analysis employed show that the present model can describe clearly the behavior of rock mass and is promising for engineering application.
