摘要
在分析总结巷道围岩分区破裂机理研究现状的基础上,阐述了深部岩体特性对巷道破坏和支护的影响,探讨了现有支护荷载理论用于深部岩体工程的局限性。进一步分析了深部巷道支护方法对有分区破裂化倾向的深部巷道围岩的适用性,并针对深部工程的复杂物理力学特性和地质环境条件,提出了动态联合支护理念。
Based on research status on zonal disintegration mechanism of deep surrounding rock.The influence of deep rock characteristic on roadway destruction and supporting is summarized,and the limitations of existing supporting load theory of deep rock engineering are discussed.The supporting method applicability for deep surrounding rock with zonal disintegration tendency is analyzed.Due to complex condition of physical and mechanical properties and geological environment in deep rock engineering,the concept of dynamic combined support is put forward.
