摘要:夸斯顿(HKirSten)先生在其论文中,闸述了把初期支护明确地定量后,隧道工程中围岩情况予见性方面的问题才能解决。论文扼要阐明把挪威Q指数(岩石类别)系统与NATM(新奥法)原理合二为一能给初期支护定量,并对德尔佛(DeLver)街电缆隧道的岩心数据做了重分析,显然,昔日施工的初期支护用Q/NATM系统也同样 Abstract: In his essay, Mr. Barrisston addresses the question of the visibility of surrounding rock conditions in tunneling projects after the initial support has been clearly quantified. The paper briefly states that the combination of the Norwegian Q-index (rock type) system with NATM (New Austrian Method) can be used to quantify initial support and to reanalyze core data from the DeLver Street cable tunnel The same applies to the Q / NATM system for the initial support of the old construction
