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
