In order to research the forming mechanism of zonal disintegration, the stress distribution of surrounding rock in deep roadway was studied through three dimensional photoelastic test with stress freezing. In this work, the loads of 5, 30, 50, 70 and 90 kN were respectively applied to the axes of the roadway based on radial constraint in photoelastic test models, also the stress fields of surrounding rock were transparently presented via observing photoelastic slice. The results show that when the axial stress reaches a certain level, the stress distribution of surrounding rock of roadway is presented as concentric circles of roadway, and the stress shows its maximum near roadway. In addition, the number of stress circles increases and the level of stress improves with increasing axial stress of roadway, and the increased distance between the area of maximum stress and roadway surface can be obtained. Studies show that the range of layered fractures is determined by the magnitude of the axial stress, which is a critical influence on zonal disintegration. Furthermore, high stress 'bypass' roadway as the axial loads increases. The method of three dimensional photoelastic test brings methodological progress for the study of zonal disintegration. The research results can provide new ideas for the stability control of surrounding rock, and give a theoretical guidance for the roadway excavation and supporting design. [ABSTRACT FROM AUTHOR]
