摘要：
The effect of feet-lock bolt was studied in the rheological surrounding rock by numerical simulation. The results show: feet-lock bolt can improve the force state of vault, feet-lock bolt and grouting can improve the effect of vault stress state better in weak rock. After invert is applied, invert become the main load-bearing structure, the function of feet-lock bolt is greatly reduced after invert applied.
