摘要
为使隧道工程方案和施工计划经济、合理,使用新奥法进行施工组织设计,在工程施工中要充分利用和发挥围岩的自承能力,首先要对隧道岩体进行围岩分级,可使用围岩分级(BQ值)法、围岩分级(Q值)法、围岩分级(RMR值)法。文章主要分析了这三种方法相应的计算方法,得出相应的结论,旨在解决围岩分级繁杂、不统一的问题,为施工开挖提供有效理论依据。
In order to make the tunnel engineering scheme and construction plan economical and reasonable,the New Austrian Tunneling Method is used for construction organization design.In the engineering construction,the self-bearing capacity of surrounding rock should be fully utilized and brought into play.First of all,the surrounding rock mass of the tunnel should be classified.The surrounding rock classification(BQ value)method,surrounding rock classification(Q value)method,and surrounding rock classification(RMR value)method can be used.The corresponding calculation methods of these three methods are mainly analyzed to draw corresponding conclusions.The purpose is to solve the problem of complicated and inconsistent classification of surrounding rock,and to provide effective theory basis for construction excavation.
