在硬岩中开挖隧道,尽管从来不会有任何东西可以代替经验,但无疑应用某一种岩石分类表与数学模型分析技术相结合的方法,可在许多实际问题中有助于工程师.这类方法可以应用到不同的程度:一种是为了检验工程的可行性,在原始现场数据的基础上给加固岩体的投资以初步的评估.其它的和更令人满意的应该是加固详细设计,它不仅基于现场调查报告 While excavating a tunnel in hard rock, although there will never be anything that can replace experience, there is no doubt that applying a method combining a rock classification table with mathematical model analysis techniques can help engineers in many practical problems. The method can be applied to different extents: One is to test the feasibility of the project, based on the original site data, a preliminary assessment of the investment in reinforced rock mass. Other and more satisfactory should be reinforced detailed design , it is not only based on the site investigation report
