【摘要】 针对近年来出现的将矿山地下采空区改建为商用地下空间工程问题,探讨了利用地下采空区作为地下空间工程中存在的关键性问题,尤其在采空区长期稳定性方面,基于流变扰动导致岩石损伤室内试验,将岩石"弱化"规律引入到数值模拟采空区长期稳定性分析中,对地下采空区改造为地下空间工程提出了应注意的问题和解决途径;并简单探讨了改建过程及后期运营需要的相应加固与支护方式。更多还原

【Abstract】 The key problem of how to use the underground mined out area as underground space project is discussed to address the question of the underground mined out area being rebuilt into commercial underground space project in recent years.Especially in the long term stability of underground mined out area,based on the laboratory tests on rheological and disturbance causing damage to rock,the rock weakening rule is introduced in numerical simulation analysis of the long-term stability of underground mined out area and the problems needing attention and its solutions are proposed in the process of the underground mined out area being converted into underground space project.Also,the corresponding reinforcement and support ways for the rebuilding process and its subsequent operation are explored.更多还原
