针对地下巷道工程稳定性问题,基于岩石工程系统(RES)理论,提出了全耦合分析法及优化设计思想.首先简要地叙述了全耦合分析过程的思想及流程,并在收集的27个样本的基础上,应用神经网络编码法建立了地下巷道工程的综合交互作用矩阵(GIM),分析了主要因素影响和作用机制.根据本巷道工程系统的稳定性能分析结果,提出了稳定性评价参数,给出了稳定状态范围.针对沙曲煤矿顺槽进行了优化支护设计举例,并用Q系统岩体质量评价法对其进行对比分析及验证.现场监测及对比分析结果表明,提出的全耦合分析法对稳定性分析及支护设计方法有实用价值.

Study on full coupling analysis method for stability of underground roadway engineering based on RES

Based on rock engineering system (RES) theory, a full coupling analysis method and optimization design idea for the stability problem of underground roadway engineering are put forward. At first, the full coupling analysis method and flow are described briefly; and then collecting twenty-seven lithology samples. Global interaction matrix （GIM）of roadway had been made up by artificial network coding method; and the main influential factors and effect mechanisms had been analyzed. And then the stability evaluation parameters are proposed from the results of stabilization capability analysis; and the stability state ranges are given. At last, taking Shaqu Coal Mine for example, stabilization analysis and supporting optimization design are made; and the Q system is applied to appraise rock body quality for contrast analyze and validate the design result. All the results show that the full coupling analysis method has practical value for stability analysis and supporting design.
