| 摘 要： | 由于采空区对原有岩体应力平衡的破坏,可能导致地面塌陷等地质灾害,威胁地表建筑、工程的安全。为研究深圳鹏茜大理岩矿采空区的稳定性,采用Flac3D建立三维数值模型对采空区围岩的应力、位移和塑性区进行了分析;同时,针对鹏茜大理岩矿不同倾角岩层段上、下水平矿柱的稳定性进行了计算。综合研究结果表明:鹏茜大理岩矿采空区整体稳定性良好。

| Abstract: | The destruction of the original rock mass’s stress equilibrium by goaf may lead to ground collapse and other geological disasters.It might threaten the safety of surface buildings and projects.In order to study the goaf’s stability of the Pengxi Marble Mine in Shenzhen,Flac3D is used to establish a three-dimensional numerical model to analyze the stress,displacement and plastic zone of goaf’s surrounding rock.Meanwhile,the stability of horizontal pillars in strata with different dip angles of Pengxi Marble Mine is calculated.The results indicate that the overall stability of goaf in Pengxi Marble Mine is good. |
