1981年在亚洲举行的一次掘进技术学术讨论会上,欧洲的专家们介绍了新奥法的优点,并听取了日本在这方面的经验。会上还谈到了注浆监控技术及使用钢纤维喷射混凝土等题目。其中心议题为“地下建筑工程中的现代技术”。 一、新奥法的基本原则 会上有新奥法专家高尔瑟(Golser)介绍了新奥法的基本原则。他说,掘进时地下峒室围岩可以形成一个承载圈,本身具有支护作用。在掘进过程中,岩石的应力在原始平衡状态中发生多次重新分布和变更。他认为新奥法的作用,在于它以一种经济和在技术上很安全的优点,对上述变化过程发生
At an excavation technology symposium held in Asia in 1981, European experts introduced the virtues of the new Austrian law and listened to Japan’s experience in this field. Also talked about the grouting monitoring technology and the use of steel fiber shotcrete and other topics. Its central theme is “Modern Technology in Underground Construction.” I. Basic Principles of the New Austrian Law There are new Austrian law experts Golser (Golser) introduced the basic principles of the new Austrian law. He said that during excavation, the surrounding rock of the underground locknuts can form a bearing ring, which has the function of supporting itself. During the excavation process, the stress of the rock is redistributed and changed several times in the original equilibrium state. In his opinion, the role of the new Austrian law lies in that it takes place on the above course of change in an economically and technically safe manner
