| 中文摘要 | 为了揭示深部高应力岩体工程中所体现出的围岩分区碎裂化现象的机理,采用模拟试验的方法,研究了高应力作用下材料性质,支护,试件尺度对围岩分区碎裂化产生的影响。结果表明:所做的相似材料模拟试验,在洞室周围都观察到了围岩分区碎裂化现象;围岩分区碎裂化形成的应力条件与材料性质有关,脆性材料中更易出现分区碎裂化现象;洞室的破坏程度与支护有关,在有支护条件下,断裂间距减少,破裂程度减弱;试件的长度对分区碎裂化现象的产生影响不明显。该成果对深部高应力岩体工程具有一定的参考价值和指导意义。; For the sake of bringing to light the mechanism of the zonal disintegration,we study distortion characteristic of similar material hole room by the high stress load,and research the influence of the axial load,the supports protections and the test sample length aspects.The result indicates,the zonal disintegration phenomenon is observed in this simulated test;the zonal disintegration is affected by the material character,and the zonal disintegration is easy to emerge;in the brittleness material,the distortion degree is related to the supports and protections,the space of fracture is reduced under the condition of support;the zonal disintegration is not affected by sample length.The result has important guiding sense to the deep highstress rock mass engineering. |
