隧道工程岩体分级回顾与展望

Review and Prospect of Rock Classification in Tunnel Engineering

隧道工程岩体分级是认识隧道工程岩体属性的基础,对隧道工程设计理论、设计计算参数、合理施工方法及施工工艺选择具有重要的指导作用。文章对国内外隧道工程岩体分级的发展历程进行回顾,在介绍国内两个典型隧道工程岩体分级的基础上,提出今后乃至未来一段时间内隧道工程岩体分级的发展趋势。

Rock mass classification is the basis for understanding the properties of rock masses in tunnel engineer⁃ing,and plays an important guiding role in tunnel engineering design theory,design calculation parameters,reason⁃able selection for construction methods and construction techniques.This article reviews the development history of rock mass classification in tunnel engineering both domestically and internationally,introduces two typical rock mass classifications in tunnel engineering,and proposes the development trend of tunnel engineering rock mass clas⁃sification for the future and beyond.
