基于《NATM》原理的隧洞施工方法正在我国试点并逐步推广,在以“新奥法”施工的地下洞室中,观测工作是一个重要的组成部分.但在我国,地下洞室的现场观测还是一个薄弱环节.作者在本文中简单地综述了《NATM》的基本思想和指导原则;阐述了现场观测的意义,比较全面地列举了现场观测的内容,介绍了日本“名盐”隧道的观测结果,在文中还着重介绍了日本神户大学教授樱井春辅提出的用“应变”做为破坏准则的“直接应变控制法”来评价洞室稳定性的方法.
The tunnel construction method based on the “NATM” principle is being piloted and gradually promoted in China. Observation work is an important component in underground caverns constructed with the “New Austrian Law”. However, in China, the on-site observation of underground caverns is still A weak link. In this article, the author briefly reviews the basic ideas and guiding principles of NATM, explains the significance of on-site observations, and gives a comprehensive overview of the contents of on-site observations, and introduces the observation results of Japan’s famous salt tunnels. This article also focuses on the method of assessing the stability of caverns using the “direct strain control method” proposed by Professor Sakurai Haruhiko of Kobe University in Japan.
