摘　　要：通过对马头门的破坏机理进行理论分析,采用三维弹塑性有限元方法模拟了马头门的支护,研究了3种支护情况对马头门结构稳定性的影响,认为锚杆对围岩有不可忽视的加固作用,同时得出单一的刚性支护或单一的柔性支护都不适用于该马头门,比较理想的支护方式是先柔后刚的二次支护的结论。所得结论为合理选择设计方案提供了理论依据,对工程的设计和施工具有一定的指导意义。Based on theoretic analysis of the horsehead failure mechanism, horsehead support is simulated with finite element method of three dimensional elastic-plasticity, and the effect of horsehead's stability under three supporting circumstances is also studied. It is considered that anchor rod's consolidating function for adjacent rock can't be ignored. Moreover neither single-rigid supporting nor single-flexible supporting is applicable to the horsehead, while secondary supporting of putting flexibility before rigidity is relatively ideal. This resulting conclusion offers the theoretic basis for selecting design schemes properly and has the specific significance for works' design and construction.
