【摘要】 地表砂浆锚杆是浅埋隧道工程常用的地表加固措施,在实际应用中由于普通砂浆锚杆的局限性,往往达不到预期加固效果。考虑到中空注浆锚杆的优势,尝试采用中空注浆锚杆替代普通砂浆锚杆,并通过具体工程实践和有限元模拟,进一步论证了地表中空注浆锚杆的优越性。更多还原

【Abstract】 The surface mortar bolt is a commonly-used surface reinforcement measure in shallow tunnel engineering. In practical application,due to the limitations of ordinary mortar bolt,it often cannot achieve the expected reinforcement effect. Considering the advantages of hollow grouting bolt,the hollow grouting bolt is attempted to replace ordinary mortar bolt, and the advantages of surface hollow grouting bolt are further demonstrated through specific engineering practice and finite element simulation.更多还原
