前言所谓新奥法,就是在地下工程中采用光面爆破掘进,系统地应用喷射混凝土、锚杆、挂金属网等主要手段,积极利用围岩自身所具有的强度,以求围岩稳定的一种方法。自从新奥法问世以来,已在岩体工程界引起了极大的重视。应用新奥法原理进行隧道工程设计和施工,使岩峒在发生破坏之前限制围岩的变形,以改善峒体应力状态,提高岩体强度,达到充分发挥围岩的自稳能力。新奥法量测技术不仅能预测施工中塌方的可能性,并可防止竣工后的变异。隧道的围岩稳
Preface The so-called new Austrian law, that is, in underground engineering using smooth blasting tunneling, the systematic application of shotcrete, bolt, hanging wire mesh and other major means of active use of the rock has its own strength, in order to rock stability of a Kind of method. Since the advent of the new Austrian law, it has aroused great attention in rock engineering. The new Austrian law is applied to the design and construction of the tunnel project to limit the deformation of the surrounding rock before the rock is damaged so as to improve the stress state of the rock mass and increase the strength of the rock mass so as to fully exert the self-stabilization ability of the rock mass. The new Austrian method of measurement can not only predict the possibility of landslides in construction, but also prevent the variation after completion. Tunnel rock stability
