全耦合分析法在巷道安全评价中的应用

针对巷道工程安全稳定性问题,基于岩石工程系统(RES)理论,提出了全耦合分析方法.根据全耦合分析思想及流程,并在收集的样本的基础上,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,认为岩体结构、开采深度和地下水为主要影响因素,并且给出了以开采深度为主要作用的总体正反馈机理路径.最后,应用全耦合方法对沙曲矿进行稳定性分析及优化设计,现场应用及监测结果表明全耦合分析法在巷道安全评价中具有较高意义.图5,表2,参9.

Appliance Research of the Full Coupling Analysis Method for Roadway Engineering Safety Evaluation

The authors put forward that full coupling analysis method and optimization design idea for the safety problem of underground roadway engineering,on base of rock engineering system (RES) theory.The paper interpreted briefly full coupling analysis method and flow,and collected lithology swatches.Gobal interaction matrix of roadway had been made up by artificial network coding method.The result indicate that there main influence factors are rock mass structure,mining depth and underground water state.And gobal positive and negative effect mechanism path is analyzed. At last,the authors apply full coupling analysis method to analyze roadway stability and optimize design.The result of engineering application show that the full coupling analysis method have practicality guidance value to roadway stability evaluate and supporting design guidance.5figs.,2tabs.,9refs.
