摘　　要：为验证高地应力掘进巷道锚杆支护效果,结合巷道施工现场实际情况提出优化锚杆支护方案,并布置测点和仪器对巷道表面位移和锚杆受力进行监测。分析监测结果得出:支护前期巷道位移量和锚杆受力均较大,支护完成后逐步趋缓并最终达到稳定状态,有效控制了围岩变形,达到了预期的支护效果。In order to verify the bolt support effect of high ground stress driving roadway,combined with the actual situation of roadway construction site,an optimized bolt support scheme is put forward,and measuring points and instruments are arranged to monitor the roadway surface displacement and bolt force.The analysis and monitoring results show that the roadway displacement and bolt force are large in the early stage of support,gradually slow down and finally reach a stable state after the completion of support,which effectively controls the surrounding rock deformation and achieves the expected support effect.
