摘要
以隧道施工经验和岩体力学的理论为指导原则,介绍了锚杆、格栅钢架和喷射混凝土组合的支护技术,以及微差光面爆破的掘进技术,通过监测控制围岩变形,充分发挥和保护了围岩的自承能力,总结了隧道施工必须注意的事项,从而确保隧道施工安全顺利进行。
Taking tunnel construction experience and rock mechanics theory as guiding principle, it introduces the mingled support technology of anchored bolt, grille-type steel tress and shoterete, and the digging technology of short-delay smooth blasting. It controls surrounding rock deformation through monitoring, which brings into full play and protects the self bearing capacity of surrounding rock. It summarizes the attendons in tunnel construction, so as to guarantee the tunnel construction.
