英文摘要:
      [ ] In order to study the weak interlayer effect on the bearing structure and stability of the roadway surrounding rock, based on the similar material simulation and theory analysis method, through three different schemes comparison analysis under different supporting structure stress and deformation of roadway surrounding rock containing of weak intercalations, reveals the mechanism of roadway surrounding rock stability control, including weak intercalated and validated by the measured on site.The results show that: 1) the damage degree of roof and side of roadway is obviously greater than that of shoulder;2) the combined support of scheme 3 can effectively improve the surrounding rock stress and bearing capacity of the roadway;3) the combined support scheme can make the weak interlayer and the upper and lower hard rock stratum synergistic coupling load bearing, reduce the roadway surrounding rock deformation.
