新奥地利隧道设计施工法(简称新奥法) 并不是一般的喷射混凝土支护方法,它是一种设计、施工、监测相结合的科学的隧洞建造方法。喷射混凝上、锚杆和现场监控量测被认为是新奥法的三大支柱。至今,新奥法在世界各国的隧洞和地下工程建设中获得了极为迅速的发展,特别在困难地层条件下修建隧洞以及控制高挤压变形方面,显示了很大的优越性。一、新奥法的发展与基本原则新奥法是由奥地利Rabcewicz在总结隧洞建造实践经验基础上创立的。它的理论基
The new Austria tunnel design and construction method (abbreviated to the new Austrian method) is not a general method of shotcrete support. It is a scientific method of tunnel construction combining design, construction and monitoring. Spray coagulation, bolts and field monitoring measurements are considered to be the three pillars of the new Austrian law. So far, the new Austrian law has achieved extremely rapid development in the construction of tunnels and underground projects in various countries of the world. It has shown great advantages especially in the construction of tunnels under difficult strata conditions and control of high extrusion deformation. I. The development and basic principles of the new Austrian law The New Austrian law was founded by Rabcewicz of Austria on the basis of summarizing the practical experience of tunnel construction. Its theoretical basis
