摘　　要：文章的目的在于揭示深水平近距离巷道之间各自集中应力的相互叠加(耦合)所引发的变形效应。依据岩石的流变理论、松动圈理论等相关的弹塑性力学理论,利用计算机数值模拟软件FLAC3D对安徽淮南朱集矿一深水平巷道进行了较为细致的数值分析,研究了深井高地应力下巷道掘进次生应力在相邻巷道群的显现效应的情况,揭示了相邻巷道间应力叠加所引发的剧烈变形,为深井高地应力巷道次生应力在相邻巷道群的显现效应分析提供依据,对建立相关力学理论模型和定量分析计算邻近既有巷道围岩稳定性、合理设计地下巷道群的相互位置和有效控制超深井巷道的变形都具有重大理论意义。This article aims to reveal the deformation effect caused by the mutual superposition （coupling） of concentrated stress between horizontal deep close roadway .According to the rock rheological theory ,loose circle theory and relevant theory of elastic-plastic mechanics ,the essay carried on the detailed numerical analysis of deep roadway which is one of Zhu Ji mine of Huainan city in Anhui province by use of computer numerical simulation software FLAC3D .This paper studies apparent the effect of roadway drivage secondary stress under high deep geo-stress in adjacent tunnel group .Furthermore ,the article reveals the intense deformation caused by the stress superposition between adjacent tunnel ,and provides the basis for apparent effect analysis of roadway secondary stress under high deep stress in adjacent tunnel group .It has great theoretical significance not only to establish related mechanics model as well as quantitatively analyses and calculate stability of adjacent existing roadway surrounding rock ,but also to reasonable design each position of underground roadway group and effectively control roadway deformation of the ultra-deep mine .
