摘　　要：针对地下工程难支护问题,基于岩石工程系统(RES)理论中的关键机理路径分析法,提出了一种锚固设计的理念。然后在结合实例的基础之上,根据各因素之间的关系建立了二元交互作用矩阵;并应用关键机理路径分析算法进行耦合过程获得了关键路径收益值和反馈回路,第一次提出了良性循环作用路径这一概念。最后,针对某矿区一采准巷道确定了主要承载区和支护参数。数值分析和监测结果表明,支护达到了预定的效果。In allusion to the problem of difficult supporting for underground engineering, the paper put forward a new anchoring design concept base on the critical mechanism path analysis in the theory of rock engineering system （RES）. Then, according to an engineering example a binary interaction matrix is established according to the relations of every two factors, the critical path gain values and the feedback loop path are got in full coupling by the critical mechanism path arithmetic, and the concept of well circular mechanism path is put forward firstly. At last, the load beating areas and supporting parameters for some mine are determined. The results of numerical simulation and site monitoring indicate that the supporting project achieve the prospective effect.
