摘要为研究锚固支护对钻爆法施工深部巷道围岩分区破裂的影响，采用深部巷道围岩破裂机制与支护技术模拟试验装置，开展高轴地应力条件下锚固支护深部巷道爆破开挖三维相似物理模型试验。爆破开挖、轴向超载完毕，模型巷道洞周围岩径向拉应变和径向压应力均呈现出波峰与波谷的波浪变化，与未支护模型巷道洞周径向拉应变变化规律相似，表明锚固支护模型巷道依然存在分区破裂的趋势。与未支护模型试验结果对比，锚杆和锚索联合支护的模型巷道在锚固支护部位未出现分区破裂现象，分析得出锚杆和锚索的联合作用可实现围岩应力的转移和重分布。研究结果表明，锚固支护对抑制深部巷道分区破裂具有重要的作用。

Abstract：To investigate the effect of anchorage support on zonal disintegration in deep tunnel excavated by drilling and blasting method，three dimensional physical model experiment under high axial geo-stress and blasting excavation conditions was carried out by deep rock breakage and supporting technique model test apparatus. After blasting excavation and overload in axial direction，both radial tensile strain and radial compressive stress around anchored model tunnel presented a non-monotonic change of distribution with peaks and troughs，which is similar to the model experiment results without the anchorage support. The results indicate a tendency of inducing zonal disintegration in anchorage model tunnel. Compared with the model experiment results without anchorage support，there is no zonal disintegration phenomenon in anchorage positions of model tunnel supported by combination of anchor bolt and anchor cable. Therefore，combination of anchor bolt and anchor cable can transfer and redistribute the stress of surrounding rock. Hence，anchorage support plays an important role in restraining the zonal disintegration.

Key words： rock mechanics deep rock zonal disintegration anchorage support blasting excavation model experiment
