摘　　要：为了掌握井下巷道开挖后围岩破坏区的分布情况,基于现场围岩层状赋存特征和应力场的非均匀分布特性,建立了层状围岩条件下巷道围岩区域受采动及地质构造影响下的统一受力模型,并通过计算机编程实现了复杂应力场中巷道围岩破坏区的可视化。通过与FLAC3D数值模拟结果的对比分析验证了可视化程序的可靠性,并在现场十几个矿区的巷道围岩稳定性分析及巷道支护参数设计中得到应用,取得了良好的应用效果。The shape and distribution of the surrounding rock failure zone directly determine the stability of the, roadway, and it is also the foundation of the design of roadway support. In order to grasp the .distribution characteristics of rock damage zone after the tunnel excavation, based on the layered occurrence characteristics of surrounding rock and the inhomogeneous distri- bution feature of stress field, the unified force model of the surrounding rock area under the influence of mining dynamic and geological structure is established. Then the visualization of roadway surrounding rock failure zone in complex stress field is achieved through computer programming. And the reliability of the is verified by FLAC3D numerical simulation comparison analysis. The visualization program has been applied in the field of more than a dozen mining area of roadway surrounding rock stability analysis and roadway support parameters design, and good results have been achieved.
